The following guidelines will improve performance and provide longer operating times for the
GMR-GPS unit:
1. Do not mix old and new batteries.
2. The use of alkaline-type batteries is recommended to provide the longest operating time.
3. Do not mix alkaline, standard (carbon-zinc) or rechargeable (NiMH) batteries.
4. If the unit is not to be used for an extended period of time, remove the batteries. Old or
leaking batteries can cause damage to the unit and will void the warranty.
Using Rechargeable Batteries or Vehicle Cigarette Lighter Battery Elimina-
tor:
When rechargeable batteries are installed in the GMR-GPS unit, they can be recharged by placing
the unit on the optional charging stand, Part Number GMRGPS-SC.
CAUTION: The optional charging stand is intended for use only with Audiovox-approved rechargeable
(NiMH) batteries (P/N GMRGPS-BT). Avoid overcharging the batteries, or else battery
life will be shortened.
In addition, the unit can be operated from a 12 Vdc source (such as available from a car cigarette
lighter receptacle) only by connecting the optional vehicle cigarette lighter battery eliminator to the
DC6V jack on the lower right side of the unit. When connected for operation in this manner, the
batteries are bypassed and are no longer used to power the unit. The battery charge indicator icon
displays the battery charge level.
CAUTION: Direct application of 12 Vdc will cause damage to the unit.
Full Battery - Three segments illuminated.
