ClearLink 905 Owners Manual


Thank you for purchasing ClearLink Communications Family Service Radios.

ClearLink Communications is dedicated to innovation and excellence in wireless
communications, especially in the emerging area of "Family Radios" and related products.

"Family Radio Service."

The Federal Communications Commission (FCC) introduced "Family Radio
Service" in 1997 to provide the general public with broader access to short range, two way voice


To prevent interference with military and commercial radio systems, Family
Radio Service is limited to a maximum of 14 channels which operate on specific FCC assigned frequencies.
In addition, output power is limited to 500 mw. While the normal operating range is approximately one mile,

under ideal conditions Family Radios will operate within a range of up to two miles.

All Family Radios, including the ClearLink 905, are programmed to transmit and receive regulated signals
only on FCC assigned frequencies. Any attempt to modify either these signals or frequencies is in violation of
FCC regulations and may cause permanent damage to the radio.

Operation is further subject to the following conditions as established bythe FCC:

1. Family Service Radios may not be used to cause harmful interference with
other radios;

2. Individuals operating Family Service Radios must acknowledge that these

radios may be subject to occasional interference from military and commercial systems.

We offer several models of Family Service Radios, including the ClearLink

The ClearLink 905 operates on the 14 FCC assigned channels.  Each channel has 38 CTCSS (Continuous
Tone Coded Squelch System) often referred to as Privacy Codes for a potential of 532 private conversations.

This manual provides operating instructions, specifications and other important information pertaining to the
ClearLink 905.

Installing The Batteries.

The ClearLink 905 is powered by three AA alkaline batteries. This model can also be powered by an
optional, rechargeable battery pack or by optional, rechargeable AA Nickel Cadmium (NiCad) batteries. See

"Optional Accessories" at the end of this manual for further information.

To access the battery compartment on the back of the radio, slide the compartment cover downward and

remove it. Insert three AA batteries (not supplied) in accordance with the polarity symbols (+ / - )
embossed on the bottom of the compartment, and replace the compartment cover.

The radio is now ready to transmit and receive.

Worth Noting:


If the red Low Battery warning indicator illuminates on the LCD screen when the radio is turned on,

it is time to replace the batteries.


When replacing the batteries, always replace all three.

"Turning It On."

To turn the radio on, turn the Power ON/OFF button (# 2) in a clockwise

direction. The radio will emit a series of short "startup" tones indicating that it is ready to transmit and

"Tuning It In."

ClearLink 905.

The ClearLink 905 operates on the 14 Channels Licensed by the FCC for license-free communications.  Each
of these channels has 38 associated CTCSS codes.

“Selecting a Channel”
In standard operating mode the “UP”(SCAN) or “DOWN”(ME) buttons will change the channel.  Once the

desired channel is selected you are ready to communicate.

“CTCSS or Privacy Codes”
A Continuous Tone Coded Squelch (CTCSS) or privacy code may be used to decrease the interference from
other radios in the same area. There are 38 tones available on each channel to activate:



Press the “CTCSS” button.  The “CTCSS” icon will appear on the display and CTCSS code will flash.



Press the “UP” or “DOWN” buttons to select the desired CTCSS code.  Press the “PTT” button to



A code of “00” means that no code is programmed.


You must set CTCSS for each of the channels you want to use CTCSS on.

"Avoiding The Competition."

The ClearLink 905 has two SCAN modes.  The first and most popular is the “BUSY” SCAN during which the
radio will stop on occupied channels.  The radio will remain tuned to that channel for approximately 5
seconds.  The second SCAN mode is the “FREE” SCAN mode, which searches for and stops on unoccupied


Accessing “BUSY” SCAN


Press and release the “F” button then press and release the “UP” button.  The SCAN icon will be

displayed and the unit will now begin scanning through the channels.



Pressing the “UP” or “DOWN” buttons will determine the direction of the scan either lowest to
highest channel or highest to lowest channel.



Pressing the “PTT” button returns the radio to normal operation.



To exit this scan mode press “F” and the “UP” button.  The SCAN icon should disappear from the


Accessing “FREE” SCAN



Press and release the “F” button and then press and hold the “UP” button for 5 seconds.  The
BSCAN icon will appear on the display and the unit will begin to scan for blank channels.



Pressing the “UP” or “DOWN” buttons will determine the direction of the scan either lowest to
highest channel or highest to lowest channel.



Pressing the “PTT” button returns the radio to normal operation.



To exit this scan mode press “F” and the “UP” button.  The SCAN icon should disappear from the

“Transmitting & Receiving.”

To send a voice transmission, depress and hold the PTT Button down. The red TX/BATT indicator light will
illuminate confirming that the radio is in the transmission mode. Hold the Microphone (#7) approximately

two inches from your mouth, and speak in a normal voice. When you are finished transmitting, release the
PTT button; the radio will automatically revert to the receive mode.

"Call" Button.

To alert the operator of another radio that you are about to send a transmission, press and release the Call
Button (# 4). The "call signal" will sound in both the transmitting and receiving units for approximately two


This "call signal" will be heard in other radios with which you are operating only when they are turned on.

"Roger" Signal.

The radio can be programmed to transmit a brief signal to the other radios with which you are operating

when you end your transmission. To activate this feature, with the radio OFF depress and hold the “DOWN”
or “ME” button turn the radio ON and release the buttons.

This feature will be retained in memory and will return to the selected choice when the radio is turned OFF
and ON.

Adjusting The Volume.


background image

To adjust the volume, turn the Volume Control Button (#2) clockwise (volume up) or counter clockwise

(volume down). To determine the current volume level prior to turning the radio on, depress and hold the
Monitor Button (#6). The Speaker will emit static approximating the current volume.

Battery Indicator
The Battery condition indicator located on the display, will show the amount of charge in the batteries

powering the radio.  Replace alkaline or recharge NiCad batteries as soon as possible after this signal shows
less than two segments lit.

Battery "Reserve" Feature.

In order to reserve battery power, the radio is programmed to cycle from a fully operational mode to a
standby mode if no transmissions are sent or received within a period of approximately six seconds. The

cycle is continuous, and is interrupted whenever a transmission is sent or received.

This feature increases the useful battery life by approximately 50%.

Belt Clip & Adjustable Wrist Strap.

To install the Wrist Strap, thread the thin end of the Strap through the hole at the top of the Belt Clip

creating a small loop. Thread the other, thicker end of the Strap through the small loop and pull the Strap

To remove the Belt Clip from the back of the radio, pull it gently out and down.

Display Backlight

Press and hold the “F” button for 5 seconds.  A beep will be heard.  The backlight will remain on for
approximately 5 seconds and will turn off to save battery power.

Key Lock

To avoid accidental channel changes the keypad may be locked.  To lock, Press the “F” button and then
press the “M” (Monitor) button.  The KEY icon will appear in the display.  In this lock mode only the PTT,
CALL and “F” buttons are active, if any other button is pressed 3 quick beeps will be heard.

To unlock, press “F” and then press “M”.  The KEY icon will disappear.
