Note: retain the cover plate and screws for future use. Remove the two M4 x 10 lower rear panel

screws (to be re-used in step 6) and pole mount thumb screw (figure 1).

3 Align the battery as in figure 2 and set its legs in the bottom of the EX20 or EX30 as in figure 3.

4 Connect the Battery supply cable as in figure 3. IMPORTANT! Both the connectors on the supply cable

(from the battery) and connector plug (on the cabinet) are keyed. Be sure to connect the cable cor-

rectly or you’ll risk shorting the battery which may result in fire and/or internal amplifier failure.

5 Lift the battery into place and screw the two M4 x 14 screws into the two outer holes and the two M6 x

12 screws in the inner holes on the battery lip. Use the two M4 x 10 screws (from step 2) to secure the

bottom of the battery to the cabinet.

Charging the Battery

Before using the RB2030, the Battery must be fully charged. After following the instructions for installa-

tion, connect the EX20 or EX30 to an outlet and turn the unit on. The battery will take 8 hours to fully

charge initially. Subsequent full charges can be achieved in 4 hours. The battery level meter on the rear

panel of your EX20 or EX30 will show a level only when the AC cord is disconnected.

IMPORTANT: The RB2030 Battery must be fully charged after each use.
