The Transmitter and Receivers can use rechargeable AA batteries (BAT 026). On an overnight

and Receivers for 20 hours.
The battery installed in the receiver may be recharged in the receiver only if it is a Nickel-Metal
Hydride (NiMH) battery, and only if a Williams Sound CHG 1600-02 Multi-Charger is used.
Damage from improper charging is not covered by the Williams Sound five year warranty. For
charging instructions, see figure 7.

complete charge cycle before the first use (approximately 15 hours). Rechargeable batteries will
need to be replaced after 1-2 years of use. Do not dispose of batteries in fire. Do not open
