Setting Calling Tone Type
When the unit is off, press and hold the PWR/SET key and the SCAN key
simultaneously till the unit beeps. The unit’s full LCD display, showing all icons, will
light up. You can now select the call tone type.
Press the CALL key to sound the first choice of 6 different call tones available. You
can either press the CALL button again in sequence to select and sound the other
available tones or scroll through them all with the UP and DOWN buttons. When you
have the call you wish to transmit selected, press either the MOD or the SET key to
save. This tone will now be transmitted whenever you press the CALL button in
standby mode until you select another tone. Press SET key again to turn the power
off.

Optimizing Range
Your MRC-11X radio has a range of up to 2 miles for 0.5 watts, up to 7 miles for 3.0
watts under the most ideal conditions such as wide, open flat terrain. This effective
range can be shortened by signal attenuation caused by buildings, vehicles, and
other obstructions such as dense foliage and hilly terrain.
• UHF operation allows the MRC-11X to provide communication that is virtually free
of the atmospheric interference that is often common with lower frequency bands.
Additionally, higher power and an antenna system that is very efficient as compared
to other unlicensed radio bands (such as 49MHz) often used for motorcycle
communicators, further enable the farther operating range of the MRC-11X.
• Often the limits to maximum possible range are environment factors such as
blockage caused by trees, buildings, hills or other obstructions. Sometimes you may
find communication suddenly not possible (localized dropout zone), and this can
almost always be overcome by moving only a few feet to a new location. Be aware
that the range may be greatly reduced while operating in a vehicle or metal building.
• Battery condition also effects range, with fresher batteries providing greater
transmitted output power. The MRC-11X operates on rechargeable Ni-CAD or Ni-MH
batteries or ordinary alkaline batteries.
• Since the body absorbs some radiated energy, thus reducing range, note that
holding the unit in your hand, or mounting it on your bike’s handlebars (so the unit is
away from your body) will ultimately maximize range under all conditions. However,
normal mounting on your belt or clothing is often more convenient and should
provide sufficient range for most bike-to-bike communications. If maximum range is
needed, experiment with the unit placement for best performance.
Note: This unit cannot ensure privacy in communications.

Setting Functions
For all the function set modes:
• Press the MODE key to save the set number selected and enter the next set mode.
Press the PWR/SET key to save the set number and exit the set mode. Press the UP
key or DOWN key to change the set number or status. Press any other keys to exit
the set mode.
• While the unit is in standby mode, press the MOD key for 2 seconds (till unit beeps)
to enter the set mode. This allows a choice of seven different sequential modes to
set: (1) Basic channel select, (2) Basic CTCSS code number selected, (3) VOX level
select, (4) Dual channel scan, (5) Second channel select, (6) Second CTCSS code
number select, (7) Radio/Intercom or Intercom select. Press PWR/SET key anytime to
set selection and return to standby mode.
• (1) Basic channel select: While the unit in set mode, press the UP key to increase
the channel, press the DOWN key to decrease the channel. Press the MODE key
momentarily (unit will beep) to save the selected basic channel and to set the CTCSS
code for the basic channel selected.
• (2) Basic CTCSS code number selected: Press the DOWN key or the UP key to
change the CTCSS code. Press the MODE key again to save the CTCSS number
selected and to set the VOX level.
• (3) VOX level select: Press the UP key or the DOWN key to select one of the 4
different VOX sensitivity levels. Press the MODE key to save the VOX level selected
and to set the dual channel mode on or off.
• (4) Dual channel scan: Press either the UP or the DOWN key to turn the dual
channel scan on or off. Press the MODE key to save channel status and enter next
mode. When the dual channel mode is set to on, and the ( ) icon is displayed, you
can set the second channel. When the dual channel scan is set to off, proceed to (7)
Radio/Intercom mode.
• (5) Second channel select: Press the UP or DOWN key to select the channel and
the MODE key again to save the second channel and to set the second channel
CTCSS code.
• (6) Second CTCSS code number select: Press the UP or DOWN key to select the
CTCSS code and the MODE key again to save second channel CTCSS code and to
set the Radio/Intercom on/off.
• (7) Radio/Intercom or Intercom select: Press either the UP or DOWN key to
select between Radio/Intercom (both and icons displayed) or intercom (
icon) only. Press either the MODE or PWR/SET key again to save all status and exit
set mode back to standby.
