Caring for Your microTALK

®

Radio

Your microTALK

service if cared for properly. Here are a few suggestions:
• Handle the radio gently.
• Keep it away from dust.
• Never put the radio in water or in a damp place.
• Avoid exposure to extreme temperatures.

Recharging Batteries

You should fully recharge the battery pack before using
your microTALK

Attach the power supply

to the charger base and plug 
it in to an electrical outlet.
(A UK-compatible connector
is included, if required.)
Place the radio in the charger
base to begin charging. 

2.

With the optional

adapter, you can place the
battery pack alone in the charger base. Pull down the
LOCK TAB and remove the battery compartment cover.
Remove the battery pack
and place the battery pack
in the charging well.

then blink rapidly until the battery is fully charged, then
blink slowly indicating trickle charge. A full charge will take
approximately 2 hours. You can leave the unit in trickle
charge indefinitely.
