LOW BATTERIES POWER INDICATION OPERATION MANUAL
CTCSS code set
You can select any one of the 38 available CTCSS privacy (lockout) codes for each of
the 22 channels while the CTCSS icon is flashing. See pg. 16, “ Setting Functions” for
instructions for how to enter CTCSS Select mode to get CTCSS icon to flash. Press
the UP or DOWN key to select the desired code number for that channel. Press the
MOD key again to save the CTCSS number selected. Press the PWR/SET key
momentarily to exit.
Auto Squelch
This unit is equipped with an auto squelch that we’ll automatically shut off weak
transmissions and unwanted noise due to terrain conditions or if you reach the
operating range limit. It can be defeated (turned off) by pressing the SCAN key. See
also “Scan (Auto Monitoring) pg 14.
Stopwatch
To enter the stopwatch mode, press and hold the CALL key for over 2 seconds.
In stopwatch mode, press the TALK key to start count, and press the TALK key again
to stop. While the watch is stopped, press the CALL key to reset the counter, press
the TALK key to restart the watch. To freeze the LCD display while counting, press the
CALL key once momentarily. To pick up the current count, press the CALL key once
again momentarily. Press any of the other keys to exit stopwatch mode at any time
and set the unit into standby mode.
AUX (Stereo Auxiliary Audio Input) Jack
A tape player, radio or CD (or any other external music source) can be connected to
the AUX (Auxiliary In) stereo jack to allow both the driver and passenger (if any) to
also hear music while either conversing with each other or with other bikes. This
function works in any mode, and the AUX audio will not be transmitted or heard by
the other parties you are communicating with. The audio level heard needs to be
adjusted with the volume adjust knob of the music source.
Driver / Passenger + charger jacks with external PTT
The MRC-11X is specially designed with DRV/PSG+CHG jacks with external PTT
(push-to-talk) capability. Both the DRV and PSG jacks accept the MHS-11X (C or O)
headset/microphone for motorcycle, with external PTT mounting on the handlebar
(one headset is supplied with the unit). If the unit will also be used for driver/
passenger communications, an optional MO-1 or MC-1 headset for the PSG jack is
needed (see the enclosed Optional Ordering Form for Accessories). When the driver
headset is plugged into the DRV jack on the unit’s top panel, it automatically disables
the MRC-11X’s built-in Mic and speaker, and the headset must be used for all
communication. The PSG jack also accepts the external optional BC-11X battery
charger to charge the Ni-CAD or Ni-MH rechargeable batteries internally. For charging
instruction see pg. 8, “Recharging Ni-CAD or Ni-MH Batteries”.

OPERATION MANUAL
dual channels setting is selected ON, the ( ) icon appears on the display and the
unit will receive one either of the dual channel selected (basic channel and second
channel). This Dual Watch monitor mode is especially useful when the signal you
want to hear is consistently weak
Dual channels transmission: If the dual channels in on, the ( ) icon appears on the
display and the unit can transmit on either of dual channels (basic channel and
second channel). Hold down the TALK key to the transmit on the basic channel, and
press and release the MODE key and then hold down the TALK key to transmit on the
second channel (the second channel number will then appear on the display).
Radio & Intercom / Intercom
Intercom only: In the Intercom mode ( ) icon, insert the driver and passenger
headsets into the appropriate jacks on the top panel as marked on the rubber cover
plug. The driver and the passenger can then communicate with each other
simultaneously (full duplex).
Radio & intercom: In the Radio & Intercom mode ( ) icon, when the driver and
the passenger headsets are connected, the unit will automatically also be in the
Intercom mode. Both headsets will hear any received audio and both of the
microphones are able to transmit audio and trigger the VOX.
VOX (voice-activated hands-free operation)
In standby mode, press and hold the DOWN key for over 2 seconds to turn the VOX
on/off. The VOX ( ) icon appears on the display whenever the VOX mode is
turned on. To optimize the VOX operation, you can select 1 of 4 different input volume
levels for triggering the VOX, depending on the background ambient noise and your
speaking level. See “ Setting Functions”, pg. 16, for instructions for choosing the
VOX level desired.
Key Lock
The purpose of the Lock function is to lock most keys to avoid accidental operation.
In standby mode, press and hold the UP key for over 2 seconds to turn on the key
lock. The ( ) icon appears on the display. Press and hold the UP key again to turn
off the key lock. While the unit is set to the key lock status, only the TALK, UP and
SCAN keys will have any response.
Scan (Auto Monitor)
Auto Monitor: When the signal you want to hear is consistently weak, you may place
the radio in monitor mode, which will defeat the auto squelch, and thus prevent the
muting of weak signals. However, between receptions you will then also hear the
normal loud radio hiss, since the auto squelch is off. Press the SCAN key
momentarily to enter monitor mode. To return to normal operation, press any key. See
also “ Auto Squelch”.
Scan: Press and hold SCAN key for over 2 seconds to start scanning all the channels
in the up direction. To exit the scan mode and select the channel being displayed at
any point to be the basic channel, press any other key.
