For operation. The following steps accomplish installation.

1. Unpacking

2. Set-up Procedure

3.1. UNPACKING

Each component of the DC-180 system is packed in a specially designed carton.
Remove each component from its carton, separate the component from its
polystyrene shell assembly and set aside. Inspect the carton interior to be sure
that all accessories have been removed from the carton. Inspect the carton inner

panels for accessories.

NOTE: Be sure to repack all materials within the carton set. Store the cartons in
A secure area so they can be available whenever future shipment of the scale is

required.

3.2. INSPECTION

Immediately after unpacking, a visual inspection of the scale should be performed.
If any damage has been incurred during transportation notify the shipper and DIGI
MATEX, Inc. immediately. Instructions for assessment of damage and further
procedures will then be determined.

3.3. REPACKAGING

If, at anytime, the DC-180 counting scale must be returned for modification,
calibration, or repair, be sure that it is properly packed with sufficient cushioning
materials.

Whenever possible, the original carton assembly should be retained for this
purpose. Any damage caused by improper packaging will not be covered by
warranty.

3.1. UNPACKING

The unlocking procedure is included on the next page. The DC-180 should

be properly locked whenever it is being transported.

4.0. DC-180 AC / BATTERY OPERATION

The DC-180 can be operated with AC power or with the optional internal
battery. The battery will automatically charge whenever the scale is
plugged into AC power. The charging current is regulated by a battery
monitor circuit, so that the battery can not be overcharged.

The DC-180 system is powered internally at a low power level whenever
the scale is plugged into the AC line or the battery switch is in the “ON”
position. The battery power switch is located on the right side of the rear
panel. The front panel “ON/OFF” switch enables the display and
primary power.

When the battery switch is “ON” and the AC is not connected, a low level
battery current will flow even if the display is “OFF”. To prevent battery
discharge when stored turn the battery switch to “OFF” whenever unit is
not used.

Do not store the scale without turning off the battery power switch.

To Install Battery Option

1. Turn Scale On Side.

2. Remove Battery Compartment Cover.

3. Connect The Red Lead To (+ ) Positive Terminal Of Battery.

4. Connect The Black Lead To ( −)Terminal Of Battery.

5. Place Battery Into Compartment & Replace Battery Compartment Cover.

CHARGING TIME: FOR OPTIMUM USE AND BATTERY LIFE, THE DC-180 BATTERY
SHOULD BE FULLY CHARGED BEFORE EACH OPERATING RUN.

NOTE: Short Cycle Charging Will Reduce The Normal Use Time And Can Drastically

Reduce Battery Life.
The BP-180 battery is a sealed lead acid battery which needs to be charged

periodically, similar to a car battery, if the BP-180 is left on the shelf for several
months without being charged it will eventually drain to point that it can no longer be
charged!
