8. OPERATION
Step 1. Confirm that the IR-310M has been set to
the desired channel "A" or "B."
(Refer to p. 10 "CHANNEL SETTING.")
Step 2. Switch the IR-310M’s power ON and
confirm that the battery indicator lights
green.
Step 3. (When wishing to use the Function button,
which is enabled only when the unit’s
transmitting frequency is set to Channel
"A.")
Push the Function button while speaking
into the microphone.
Audio signals are also output from the IR-
801AF Audio Interface Unit, besides the
IR-801AF’s contact output is closed. (See
the next page.)
Step 4. Switch the IR-310M’s power OFF after
use.
7.2. Charging Timing
As discharge progresses, the battery indicator’s color gradually
changes from green to red. If the indicator lights red during use,
charge the IR-310M immediately since the microphone will be
disabled several minutes after the indicator has lit red.
[Guidelines on the rechargeable battery operation time]
Continuous usage time: About 8 hours
Notes
• When using the IR-200BT rechargeable battery for the first time or when using it after it has
been stored for a long period of time, be sure to charge it before use.
• The IR-200BT battery is designed to cycle through about 500 charges and discharges.
When the microphone operation interval becomes extremely short after prolonged repeated
use, change the battery with a new one.
• Do not frequently insert and remove the microphone from the charger during charging, as
this could reduce the number of times that the IR-200BT can be effectively charged and
discharged.
