Battery Replacement

The NiCad batteries need to be replaced when fully charged batteries provide less than 2 hours operation. Carefully follow the instructions below to replace the batteries.

CAUTION

Replace with only NiCad rechargeable AA batteries, IEC code KR-15/51. Nominal Voltage 1.2V; Capacity 650mAhr. Do not install alkaline batteries.

NOTE: To retain trace data stored in nonvolatile RAM, leave the AC mains adapter connected during battery replacement.

1.Lay the Antenna Tester, display side down, on a clean surface.

2.Using a small standard screwdriver, remove six screws from the back cover.

3.Lift the back cover approximately two inches above the front cover.

4.Flip the back cover in the direction of the arrow shown below. To avoid disconnecting P2, (battery connector), lay the back cover next to the front.

5.Remove the old batteries.

6.Install the new batteries checking the orientation of the positive and negative terminals. Polarity is indicated on the case, and in Figure 16.

7.Be sure P2 is connected and the shock strips are still in place.

8.Place the back cover over the front cover making sure it is properly seated.
