M2115 OWNERS MANUAL
Solutions for Advancing Communications
Installation [7]
Notice [7.1]
The first consideration for installation is to choose a suitable location. For both mobile and base installations, installation of
the M2115 radio requires connecting the radio to a suitable antenna and a suitable power source.
NOTICE: For geographic locations where lightning is prevalent, Mentor Radio
recommends installing a lightning protector on the antenna coax. If used as a base
station radio, another lightning protector on the AC line is recommended.
M2115M [7.2]
The M2115M is intended to be installed into a vehicle. A suitable location should be selected to allow viewing of the GLCD
and access to the front panel controls. A mounting bracket is provided to allow mounting the M2115M under the dash or
on any flat surface. The bracket may be installed above or below the radio. Mobile antennas are available in two
versions; a thru-hole type and a magnetic mount type. Installing a thru-hole antenna requires drilling a hole in the vehicle
or mounting on a hood or roof of a vehicle. Magnetic mount antennas require routing the coax through the vehicle door
where water may leak in or where the coax may be pinched. This may shorten the life of the antenna. Therefore, it is
recommended to use a magnetic mount antenna for short term applications where the antenna may be removed and a
thru-hole type antenna for a permanently long term applications. Install the antenna and connect to the antenna
connector on the rear panel. Some antennas for aviation band frequencies come with a UHF connector. In this case, a
UHF to TNC adapter may be used to connect the antenna to the radio.
The M2115M includes a built-in speaker. However, an external speaker may be used with or instead of the internal
speaker. If an external speaker is to be used, install 18 AWG wires to the power plug as follows: Green wire to pin 12
(Speaker audio out signal) and a black wire to pin 2 (GND). A power cable is available which includes a 6 foot speaker
cable. External speakers and cables are sold separately.
Verify that the vehicle power is not greater than 14VDC. Connect the power cable to the vehicle power or battery (Red to
“+”, Black to “-”). Connect the 12-pin connector to the rear of the M2115M radio.
