IMPORTANT SAFETY INFORMATION

1.

SAVE THIS MANUAL It contains important safety
and operating instructions for Universal Desk Charger.

2.

Before using the battery charger, read all instructions and
cautionary markings on (1) the battery charger, (2) the
battery, and (3) the product using the battery.

3.

CAUTION  - To reduce the risk of injury, charge only
Ericsson battery packs using the proper battery sleeve.
Charging any other battery pack or batteries may cause
the battery to burst and cause personal injury or damage.

4.

Do not expose charger to rain or snow.

5.

Do not use auxiliary equipment not recommended or sold
by the manufacturer. To do so may result in a risk of fire,
electric shock, or injury to persons.

To reduce risk of damage to electric plug and cord, pull
by the plug rather than the cord when disconnecting the
charger.

7.

Make sure the cord is located so that it will not be stepped
on, tripped over, or otherwise subjected to damage or
stress.

8.

An extension cord should not be used unless absolutely
necessary. Use of an improper extension cord could result
in a risk of fire and electric shock. If an extension cord
must be used, make sure:

a. That pins on the plug of the extension cord are the

same number, size, and shape as those on the
charger’s plug;

b. That the extension cord is properly wired and in good

condition; and 

c. That the wire size is large enough for the AC ampere

rating of the charger as specified in Table 1.

9.

Do not operate charger with damaged cord or plug -
replace them immediately.

10. Do not operate charger if it has received a sharp blow,

been dropped, or otherwise damaged in any way; return it
to a qualified service shop.

11. Do not disassemble the charger; return it to a qualified

service shop when service or repair is required. Incorrect
reassembly may result in a risk of electrical shock or fire.

12. To reduce risk of electric shock, unplug the charger from

the outlet before attempting any maintenance or cleaning.

 13. GROUNDING AND AC POWER CORD CONNEC-

TION - To reduce the risk of electrical shock use only a
properly grounded outlet. The charger is equipped with an
electric cord having an equipment-grounding conductor
and a grounding plug. Be sure the outlet is properly
installed and grounded in accordance with all local codes
and ordinances.

14. DANGER - Never alter the AC cord or plug. If it will not

fit in the outlet, have a proper outlet installed by a qualified
electrician. Improper connection can result in risk of an
electric shock .

15. The Rapid Charger 120 Vac line cord has a grounding

plug that looks like the plug illustrated in Figure 1. A
temporary adapter, which looks like the adapter illustrated
in sketches B and C, may be used to connect this plug to
a two-pole receptacle as shown in sketch B if a properly
grounded outlet is not available. The temporary adapter
should be used only until a properly grounded outlet can
be installed by a qualified electrician.

16. DANGER  - Before using an adapter as illustrated, be

certain the center screw of the outlet plate is grounded.
The green- color rigid ear or lug extending from the
adapter must be connected to a properly grounded outlet-
-make certain it is grounded. If necessary, replace the
outlet cover plate screw with a longer screw that will
secure adapter ear or lug to outlet plate and make ground
connection to grounded outlet.

17.  Care should be taken when placing the charger in service

to insure proper top and bottom ventilation. A minimum
of 1/4" is required between the bottom of the charger and
the surface on which it sits. 

Figure 1 - Grounding Methods

Due to the temperature characteristics of nickel-cad-
mium batteries, the batteries will not accept a full
charge at temperature extremes. For maximum capac-
ity, recharge the battery pack at a room temperature of
65° to 85 ° Fahrenheit, whenever possible.
