SD125E Description of Radio Components 1) Antenna connector 2) DB-09 connector 3) Top cover 4) DIP-S/W channel selector 5) Jumper selector Exterior View Antenna installation Fasten the antenna to the radio by turning the antenna cable clockwise onto the BNC receptacle on left of radio when looking at front of radio.
SD125E SD125E Series Operation 16 Channel select Your radio’s channel can be selected by inner DIP-S/W or serial command inputted from external control system. To change channel by inner DIP-S/W (4), you should open the upper cover and then look for the DIP-S/W (4) on the digital board of the bottom cover. Once located change the DIP-S/W to select wanted channel according to channel dip switch chart (See page 11).

SD125E Features Channel Spacing The SD-125E is capable of programmable channel spacing, in both UHF and VHF bands. Each channel can be programmed via the PC programmer, ACC-900E, having 12.5 KHz or 25 KHz channel spacing. Output Power RF Power is programmable in the SD-125E. Each channel can be programmed via the PC programmer to a high-power output, 5 Watts, or low-power output, 1 Watt. Busy Channel Lockout Busy Channel Lockout – ON: Upon PTT enable, if carrier is present, the radio will not transmit.
