Lectrosonics M170XLR - Manual (Page 7)

BATTERY INSTRUCTIONS
The battery you use in the M170 Series transmitter should be a 9 Volt alkaline, available almost
everywhere. An alkaline battery will provide 12 to 15 hours of operation. Carbon zinc batteries, even if
marked "heavy duty" will only provide about 4 hours of operation. Make sure your batteries are marked
"alkaline."
The BATTERY LAMP will light when the transmitter is turned on and will stay lit as long as the battery
is good. As the battery voltage drops, the lamp will grow dim and finally go out. Even after the lamp
goes out, there may still be up to an hour or more of operating time remaining. When the battery
voltage is too low for proper transmitter operation, the sound from the wireless system may be
intermittent or totally absent. When the transmitter is first turned on, the lamp may light for a short
while even with a bad battery. It is good practice to check the brightness of the lamp after the
transmitter has been on for several minutes and to note the brightness frequently during use.
To replace the battery, turn the thumbscrew counter-clockwise 2 or 3 turns until you can lift off the side
cover. To remove the battery, hook your fingernail under the base of the battery, press toward the
contacts and lift the base of the battery out of the compartment. It is difficult to install the battery
backwards. Observe the large and small holes in the battery contact pad before inserting a new
battery. Insert the contact end of the battery first, making sure the contacts are aligned with the holes
in the contact pad, and then press the other end of the battery into the compartment.
OPERATING INSTRUCTIONS
This section covers adjustments to the transmitter that must be made before the wireless microphone
system is placed into operation. The step-by-step procedures are listed in the order in which they
should be performed:
1) Turn the wireless receiver power on and make any required preliminary adjustments in accordance
with instructions in the receiver operating instructions.
2) Plug the microphone into the transmitter. If you are using a lavalier or headset microphone, rotate
the plug clockwise to make sure the connection is locked.
3) Turn the transmitter power on and verify that the red lamp on it lights. If the lamp is very dim or
does not light, replace the battery.
4) Observe that the RF lamp on the receiver control panel is lit. This verifies that the receiver is
receiving a useable radio signal from the transmitter.
5) Position the microphone on your person in the location it will be used during actual operation. If a
headset microphone is being used, adjust the headband for a comfortable fit with the "gooseneck" to
the left side of your head. Position the microphone element at the corner of the mouth and rotate
the white volume control fully clockwise. The headset is designed to be worn over the head, but can
also be worn around the neck. Do not position the microphone pickup directly in front of your mouth
as this may cause unwanted noise from breath pops as you speak.
