Pack.
2) Use only the Vertex Standard CD-58 Desktop Charger
and the Vertex Standard PA-55 AC Adapter.
3) To reduce the risk of explosion, recharge the batteries
outside of hazardous locations.
4) Perform the battery charging where the ambient tem-
perature range +41 °F to +104 °F (+5 °C to +40 °C).
Charging outside of this temperature range could cause
damage to the battery pack.
5) Battery Pack should not be exposed to excessive heat
such as sunshine, re, or similar heat sources.
6) Risk of explosion exists if battery is replaced by an
incorrect type. Refer to the enclosed instructions for dis-
posal of used batteries.
7) For further details and cautions of the charging, refer
