GENERAL DESCRIPTION The M170 Series transmitter is offered in five versions. The standard model is the M170. The M170-LS, M170-XLR, M170-BGO, and the M170-CTM are modifications of the standard M170. The M170 and M170-LS transmitters use the microphone cord for the antenna. The M170-XLR uses the hand-held microphone for the antenna.
When the switch is in the on position, the battery will be drained even though the transmitter is not being used. The ON/OFF switch on the M170-CTM is located on the bottom of the unit.

2 and pin 3 is connected to pin 1 (audio ground). The M170-BGO was designed specifically for use by bingo halls. A carrying strap acts as the antenna and allows the user to wear the unit around their neck. The microphone plugs directly into the top of the unit.
BATTERY INSTRUCTIONS The battery you use in the M170 Series transmitter should be a 9 Volt alkaline, available almost everywhere. An alkaline battery will provide 12 to 15 hours of operation. Carbon zinc batteries, even if marked "heavy duty" will only provide about 4 hours of operation. Make sure your batteries are marked "alkaline."...

The M170-BGO automatically shuts off when the switch is released. The M170-BGO transmitter is activated by pushing the button on the side panel. Since you are only "on the air" as long as you hold the button in, several transmitters on the same frequency will not interfere with each other.
