OPERATING INSTRUCTIONS
1) Remove the battery compartment door by
pulling the door tab towards you. Install two
fresh AA batteries, noting the polarity diagram
embossed in the battery compartment. For
continuous, heavy-duty use, alkaline batteries
are recommended.
NOTE: Rechargeable ni-cad batteries can be used
in the 49-SX. To recharge them while installed in
the unit, Maxon’s DV-7510 optional AC/DC wall
charger must be used. Average charging time is
12-16 hours.
CAUTION: Do not attempt to recharge alkaline
or carbon zinc batteries - this could result in an
explosion, or other damage to the unit.
2) Using the belt clip, affix the unit to your belt
or another convenient location. Put the headset
on, extend the antenna and adjust to a comfortable fit. Keep the microphone element within 1"
of your mouth.

3) Turn the power on and adjust the volume to a
desired listening level.
4) Position the VOX/P-T-T thumbwheel control
to either the VOX position (for hands-free, voice
activated transmissions) or the P-T-T position (for
manual push-to-talk transmissions).
When using the VOX mode, adjust the sensitivity
setting to suit your surroundings and needs. While
looking down at the unit attached to your belt,
move the thumbwheel from the low sensitivity
setting (far right) to a high setting (far left). A low
setting requires you to speak more loudly to
activate the transmitter and should be used when
background noise levels are high. A higher setting
allows you to speak in a softer voice and should
be used when lower background noise is present.
NOTE: Very high noise levels may cause the unit
to transmit continuously. When very high background noise levels are present, the P-T-T mode
may be the only method to avoid this problem.
