Operation
Speaker/Microphone/Charge Jack •
Your microTALK radio can be fitted with an external Speaker/Microphone,
freeing your hands for other tasks. This same jack also serves as the
connecting point for the wall charger/adapter.
To attach a speaker/microphone:
1. Open the speaker/microphone/charge
tab on top of your microTALK radio.
2. Insert the plug into the speaker/
microphone/charge jack.
To connect a wall charger/adapter:
1. Open the speaker/microphone/charge
tab on top of your microTALK radio.
2. Insert the wall charger/adapter plug
into the speaker/microphone/charge jack.
Signal Strength Meter •
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.
microTALK Range •
Your range will vary depending on terrain and conditions.
In flat, open country your radio will
operate at maximum range.
Buildings and foliage in the path of the
signal can reduce the range of the radio.
Dense foliage and hilly terrain will
further reduce the range of the radio.
On FRS channels 8 through 14, your radio
automatically switches to low power, which
will limit the range the radio can communicate.
Remember, you can achieve maximum
range by using maximum range
extender. See page 6 for details.

Press the Talk button at any point to return the radio to Standby mode.
Privacy Codes •
Your microTALK radio incorporates two advanced coded squelch
systems that can help to reduce interference from other users
on any given channel. CTCSS (Continuous Tone Coded Squelch
System) provides 38 privacy codes and DCS (Digitally Coded
Squelch) provides 83 privacy codes. This provides a total of 121
Privacy Codes. Either system can be used on all channels, but both
systems cannot be used on the same channel at the same time.
To successfully communicate using a privacy code, both
the sending and receiving radios must be tuned to the same
channel and to the same privacy code system (CTCSS or
DCS) and privacy code number. Each channel will remember
the last privacy code system and number you select.
The privacy code 00 is not a privacy code, but allows all
signals to be heard on a channel that is set to 00 on both
the CTCSS and DCS systems.
