PLEASE SAVE THESE IMPORTANT SAFETY AND OPERATING INSTRUCTIONS

For correct operation of the equipment, it is important to read and be familiar

with this entire manual before installing and operating the charger.

DO NOT DISCARD THIS MANUAL AFTER READING.

LOOK FOR THIS SYMBOL TO POINT OUT SAFETY PRECAUTIONS. IT MEANS:
BECOME ALERT—YOUR SAFETY IS INVOLVED.
   IF YOU DO NOT FOLLOW THESE
SAFETY INSTRUCTIONS, INJURY OR PROPERTY DAMAGE CAN OCCUR.

Features

Charger output characteristics are adjustable to charge gel cell and sealed or conventional replaceable liquid electrolyte
deep-cycle lead-acid batteries.  Different charge characteristics are selected by a switch on the front of the charger.

Patented electronic circuit monitors battery state of charge and automatically turns charger off as battery reaches full charge

Line voltage compensation produces consistent charger output for AC supply voltage variations of + 3% from nominal.

Convection-cooled design for maximum reliability and minimum maintenance.

INTRODUCTION

The Dual-Mode wheelchair battery charger is
designed to recharge deep-cycle, lead-acid batteries
of conventional replaceable electrolyte or gel cell
and sealed "maintenance-free" design.  The different
charge characteristics required by these different
types of battery design are selected by sliding the

"BATTERY TYPE" switch to the correct setting.  A
patented electronic circuit turns the charger on and
off automatically.

Batteries used on wheelchairs are subjected to
severe deep-cycle duty on a daily basis.  For this
reason, it is important that only Deep-Cycle batteries
be used.
