Battery Status LED Indicator
The Power/Function LED on the top
panel will mirror the keypad LED unless the programmable switch is set
to Mute, and the switch is turned on.
Alkaline, lithium or rechargeable
batteries can be used to power the
transmitter. The type of batteries in
use are selectable in a menu on the
LCD.
When alkaline or lithium batteries
are being used, the LED labeled
BATT on the keypad glows green
when the batteries are good. The
color changes to red at a mid-point
of the runtime. When the LED begins to blink red, there will be only a
few minutes of operation remaining.
The exact point at which the LEDs
turn red will vary with battery brand
and condition, temperature and
power consumption. The LEDs are
intended to simply catch your attention, not to be an exact indicator of
remaining time.
A weak battery will sometimes
cause the Power LED to glow green
immediately after the transmitter is
turned on, but it will soon discharge
to the point where it will turn red or
the unit will turn off completely.
Rechargeable batteries give little or
no warning when they are depleted.
If you wish to use these batteries in
the transmitter, the most accurate
way to determine runtime status is
by testing the time provided by a
particular battery brand and type,
then using the BatTime function to
determine remaining runtime.
Belt Clips
The wire belt clip may be removed
by pulling the ends out of the holes
in the sides of the case. Be sure to
have a firm grip to avoid scratching
the surface of the housing.
An optional spring-loaded, hinged
belt clip (model number BCSLEBN)
is also available. This clip is attached by removing the plastic hole
cap on the back of the housing and
mounting the clip with the supplied
screw.
IR (infrared) Port
The IR port is available on the top of
the transmitter for quick setup using
a receiver with this function available. IR Sync will transfer the settings for frequency from the receiver
to the transmitter.
Status LED
Blue LED indicates ready status.
NOTE: Refer to the Main
Menu and Setup section for
BatTime details.

MUTE
The transmitter is powered by two
AA batteries. Lithium batteries are
recommended for longest life.
The battery status circuitry compensates for the difference in voltage
drop between alkaline and lithium
batteries across their usable life, so
it’s important to select the correct
battery type in the menu.
Because rechargeable batteries
run down quite abruptly, using the
Power LED to verify battery status
will not be reliable. However, it is
possible to track battery status using the battery timer function available in the receiver.
Push outward on the battery compartment door and lift it to open.
The battery contacts can be
cleaned with alcohol and a cotton
swab, or a clean pencil eraser. Be
sure not to leave any remnants of
the cotton swab or eraser crumbs
inside the compartment.
Spring contacts
Optional Battery Eliminator
The transmitter can be powered
by external DC using the optional
LTBATELIM power supply adapter.
Slide door outward,
then lift up to open
Insert the batteries according to the
markings on the back of the housing.
If the batteries are inserted incorrectly, the door will close but the unit
will not operate.
