LED INDICATOR
The three color LED indicator on the front panel provides multiple
functions.
CHANNEL NUMBER - The LED will blink OFF a number of times
corresponding to the Channel Number when the unit is switched ON
and also when a new frequency is added to an open channel. For
example, for channel 3 the LED would blink OFF three times. After
blinking the channel number the LED will return to a steady ON
indicating normal operation.
BATTERY STATUS – During normal operation, when the LED is
GREEN, the battery is good. When the LED is YELLOW the battery is
getting low. When the LED is RED, the battery is nearly depleted and
should be replaced.
PROGRAMMING FUNCTIONS - In the programming mode, the LED
will blink at a fast rate to indicate scanning for an active frequency. It
also flashes briefly to indicate a frequency has been programmed into
a channel.
HEADPHONE JACK
On the front panel (Figure 1-2 and Figure 1-4) is a 3.5mm mini phone
jack to accommodate a standard mono or stereo type 3.5 mm plug.
The unit will drive low or high impedance earphones. The jack is also
the receiver antenna input with the earphone cord acting as the
antenna. The cord length is not critical but must be at least 6 inches
minimum.
Strain relief to avoid accidental disconnection can be provided with the
included small hook and loop strip. Attach the adhesive strip side to
the side of the receiver with the opening end of the strip up - place the
cord in the strip and secure.
