switch your unit to the same channel with the subcode set to oF.
The CTCSS subcodes do not prevent others from hearing your
transmisstion.This will only allow you to ignore all traffic on a
given channel not using the same subcode.
Rogrer Beep Tone

Remove the batteries from the transceiver if it is not expected
to be used for long periods.This will eliminate the possibility of
chemicals leaking from the batteries and corroding the
transceiver.
Avoid exposing the transceiver to water or extremes of
temperature.
Do not use this device in or near a mining facility, which uses
remotely triggered explosives or in areas labeled "Blasting
Area".
Do not attempt to modify or in any way increase the output of
this transceiver. Its output is designed to meet the legal limits.
Do not use this device or charge its batteries in potentially
explosive atmospheres. Turn your transceiver off wherever
posted notices restrict the use of radios or cellular telephones.
Facilities such as hospitals may use equipment that is
sensitive to RF energy.
Turn your transceiver off on board aircraft when requested to
do so.
Do not place your radio in front of a vehicle's air-bag. If the
air-bag deploys, it could propel the transceiver like a projectile
causing bodily injury.
Warning
To enable the channel scan mode:
- From standby mode,momentarily press the Power On/Off
Button; SCAN will appear on the LCD display.
- The radio will automatically display each channel (1-8) in
ascending order to find an active main channel.
- When the unit doesn't find any signals and you want to
transmit, press the PTT Button to return to primary channel
operation. The transceiver will automatically resume scanning
approximately 15 seconds after the communication is completed.
- If there is no activity and you want to leave the scan mode,

Power source
If you have problems with your PMR-122TX, reset your unit by
turning it off and removing the batteries. And re-insert the
batteries and turn the unit on again. Check the battery power
level since in many cases low batteries cause problems such as
no transmission, weak receiving signal and low sound.

Notes for Good Communication
1.The PMR-122TX channels are shared on a 'take turns' basis.
This means other groups may be talking on any of the
channels. A common code of courtesy is to switch to another
vacant channel and not to attempt to talk over someone who
is already using the channel you first selected.
2.The PMR-122TX has been designed to maximize performance
and improve transmission range in the field. To avoid
interference, it is recommended that you do not use the units
closer than 5 feet apart.
3.To increase battery life, use the SCAN feature sparingly. This
feature will reduce operating time considerably.
