Solutions for Advancing Communications M15- OWNER’S MANUAL M15 Solid-State VHF Aeronautical Band Radio Receiver/Transmitter Mobile Transceiver (118.000-136.975 MHz) www.mentorradio.
INTRODUCTION The Mentor Model M15 receives and transmits on up to six discrete channels in the vhf aviation band between 118 and 137 MHz (25 KHz channel spacing). It operates from a 14 v dc supply, and is intended for both vehicular and airborne application as well, and can also be used as a base station. Its advanced design features and surface mount construction provide compactness, light weight and high reliability.
INSTALLATION The M15-25 can either simply rest on a shelf or desk, or it may be mounted in a 19 inch relay rack. When rack mounted, rear support is not required. This unit does not contain a cooling fan, and does not normally need one. However, when rack mounted there should be a minimum of 1-1/4 inch above and below the cabinet to allow air circulation. When the M15-25 is located on a desk or shelf, do not place equipment, papers, magazines, etc. on top of it that would restrict its ability to stay cool.
OPERATION An on-off “rocker” type switch is in the center of the front panel. When lit, the built-in green LED indicator shows that (1) the switch is in the on position (2) the equipment is receiving power from the ac line (3) the internal dc power supply is operating. To operate, the M15 transceiver, which projects through M15-25 the rack panel, must also be turned on by rotating its volume control switch clockwise.
REMOTE OPERATION The 25 pin D-subminiature type connector on the rear panel contains all the connections needed for various types of remote operation. The functions of the different connector pins are as follows: PIN NO. 1 2 3 4 5 6 7 8 9 10 25 FUNCTION COLOR mic PTT gray mic audio violet ground black ground black ground black ground black 4 ohm rcvr out green 4 ohm rcvr out green 500/600 ohm rcvr out green squelch break blue +14 vdc yellow Connections to the mating connector can use #22 gauge wire.
MAINTENANCE No routine maintenance is necessary, other than to remove accumulated dust. If the equipment is accidentally impacted or dropped operation should be fully checked and an internal inspection made for loose or broken parts.
