PENDANT TRANSMITTERS
,1752'8&7,21
The WT-201 is a series of miniature transmitters, designed to
send coded transmissions to wireless receivers of the WR-200
and WR-300 series. Transmission is activated by depressing the
recessed pushbutton at the center of the unit. Transmitters with
an A-suffix are equipped with a 4-channel selector. The
WT-201WP is a waterproof version of the WT-201.
All WT-201 units are supplied with the chain installed, to be worn
around the neck as a pendant transmitter. A key ring is also
included in the package, for use in place of the chain. Operating
power is obtained from a cylindrical 12-volt alkaline battery
(Duracell MN-21, Golden Power GP-23A or equivalent).
A LED lights during transmission, indicating the battery voltage
condition (lights when battery voltage exceeds 8 VDC). If the LED
does not light during transmission, the battery must be replaced
immediately.
