Operation

For charging microTALK radio(s) in desktop
charger:
1.

Insert radio(s) into desktop charger as shown.

2.

Insert round connector of 120-volt adapter
into jack on back of charger.

3.

Plug 120-volt adapter into electrical outlet.

If charging light is not

on

, check position of radio. Radio should be

upright. The charge indicator light will stay

on

as long as the radio

is in the charging well, even after the batteries are fully charged.

It normally takes about 15 hours to fully recharge batteries.
Batteries will not be damaged if they stay in the charging well
longer than that.

Note:

To charge a single radio, you can bypass the desktop charger

and simply insert the wall adapter’s round connector directly into
the speaker/microphone/charge jack located on the top of the radio.

Use only the supplied rechargeable batteries and charger for
recharging your Cobra microTALK radio.

Cobra recommends your radio is turned

off

while being charged.

Non-rechargeable alkaline batteries can also be used in your radio.

Rotate the

of tones will indicate the radio is

or

Mode/Lock

buttons are pressed.

When battery power is low, the

replaced if using alkaline batteries.

Your microTALK radio has a unique circuit
designed to extend battery life. If there are
no transmissions for 10 seconds, the radio will
automatically switch to

Battery Save

mode and

the

Power Saver

icon will flash in the display.

This will not affect the radio’s ability to receive
incoming transmissions.

Your microTALK radio has a

Signal Strength

Meter

that shows the strength of your incoming

and outgoing transmissions. The ascending bars
next to the signal strength indicate the strength
of the signal. The greater the number of bars
visible, the stronger the signal. The fewer
number of bars visible, the weaker the signal.
