First Use


Power options

RD8200SG locators are shipped configured to use Li-Ion battery packs as a standard.

The transmitter can also be powered using good quality rechargeable D-cell NiMH batteries or the optional accessory Li-Ion rechargeable battery packs. It’s important to set the correct battery chemistry in the locator to optimize performance,.

Transmitters can also be powered using optional accessory mains or vehicle power adapters.


On the Transmitter:

To fit the D-cell batteries in the transmitter, unlatch the accessory tray. The battery compartment is located underneath the transmitter body. Use the turnkey to unlatch the battery compartment. Insert eight D-Cell Alkaline or NiMH batteries.

Battery status

The locator and transmitter displays provide a battery level indicator. battery status iconWhen battery replacement is necessary, the display shows a flashing battery icon.

NOTE: The locator volume may automatically lower if set to level 5 or 4, when using alkaline batteries and if their charge is low. When this happens, the display will shortly flash the ‘LOW BATT’ warning and show the reduced volume level.

NOTE: Prolonged use of maximum volume and vibration alerts on the locator will reduce battery life.

NOTE: Prolonged use of high power output on the transmitter will reduce battery life.
