Functions:

Aim Mode

When the cover is removed from the receiver, the

receiver goes into aim mode. When the cover is

removed from the transmitter, the transmitter stops

transmitting. Pressing the Aim Mode button on the

transmitter allows transmission while the cover is off.

For fine tuning which requires a measurable voltage at

the receiver, the covers must be off and transmission

is necessary.

Alarm Operation

The transmitter emits a pulsed infrared beam. The

receiver measures the intensity of the beam over a

period of time and compares this data with an alarm

threshold. Select one of six levels of sensitivity for the

alarm threshold through a switch on the receiver.

If the receiver senses signal strength below the preset

alarm threshold in excess of the alarm period it signals

an alarm.
