Recoton/Advent AW770 - Manual (Page 6)

For maximum battery life, it is recommended that you fully discharge the batteries about
once every 30 days, followed by an Extended Use charge. To discharge the batteries,
simply leave the headphones turned “ON” until the Power Indicator Light goes out.
About Batteries
WARNING: The AW770 built-in charger will charge Ni-Cd batteries only. DO NOT
attempt to recharge alkaline or rechargeable alkaline batteries as this will damage
the headphones and/or transmitter.
Over time, with repeated use, Ni-Cd batteries will eventually wear out. If, after a full
charge, you notice a) dramatically decreased playing time, b) the Power Indicator
Light begins to dim quickly and/or c) static interference occurs within a short time
of turning the headphones on, it may be time to replace the batteries.
Note: Battery life depends on frequency of use, time, and care (fully discharging
the batteries regularly, as described above.)
If you have questions regarding battery replacement, please contact our Customer
Service Department at 1-800-732-6866.
Using Optional Alkaline Batteries
The AW770 headphones can also be powered by 3 AAA alkaline batteries. You may
experience slightly longer play time with alkaline batteries but you will not be able
to recharge them, as you can with Ni-Cds.
ADJUST THE TRANSMITTER
Adjust the transmitter as follows:
Step 1 Turn ON your Audio Source (i.e. Stereo Receiver, TV, etc.) so that you
can hear sound coming from the source.
Step 2 Pivot the Antenna (O) to the upright, vertical position.
Step 3 Set the Transmitter “Level”
1. Set the Frequency Control Wheel (N) to its midpoint.
2. Turn the Output Level Control Wheel (L) all the way
to the left (your left when looking at the transmitter
controls), as shown.
3. Check status of Audio Level Indicator Light (I). If it
flickers intermittently (about half the time), proceed
to TUNE THE HEADPHONES.
4. If Audio Level Indicator Light is on solid red or
flickering very rapidly, turn Output Level Control
Wheel slowly back to the right until light flickers
intermittently.
