User's Manual

This is a high intensity indicator, visible in direct sunlight, that lights continuously
while the transmitter is generating RF output. It is located between the two
buttons. It will light even if the battery voltage is below the low battery detect
threshold.
1.6 THE BATTERY.
Power is supplied from an alkaline 9 volt battery, accessible beneath a slide-out
door on the back side of the transmitter. This battery should be replaced when
required by conditions described in section 1.3 above. In order to prevent the
possibility of damage due to battery leakage, the battery should always be
removed if the transmitter is to be stored for a prolonged period. Damage due to
battery leakage is not covered under the warranty.
1.7 THE DIGITAL CHANNEL SWITCH.
A 16 position miniature rotary switch is accessible by removing the four screws
and the back side of the transmitter. This switch is on the left edge of the internal
printed circuit board. It can be set to digital channels 0 – 9 or A – F. The
transmitter will only actuate receivers whose corresponding channel switches are
set to the same channel as the transmitter. Thus, multiple transmitters may be
used to actuate different selected receivers even though all operate on the same
frequency. All transmitters are set to channel 0 at time of manufacture.
