Using the Cradle-type Battery Charger
[Caution]
■ Ambient Temperature Ranges for the Battery Pack
• Temperature ranges for battery pack use in the Handheld Terminal,
charging, and storage are specified below. Temperatures outside these
ranges create the danger of deterioration of battery pack performance
and shortening of its service life, as well as fluid leakage and heat
generation.
Operating Temperature: –20 ° C to 50 ° C
Charging Temperature: 0 ° C to 40 ° C
Storage Temperature: –20 ° C to 60 ° C
Important! • If the charge indicator does not light during charging, remove the
battery pack and then re-attach it. If this does not solve the problem, it
means that the battery pack is defective and needs to be replaced.
• Use only the specified battery pack.
• Battery packs naturally discharge even when they are not loaded in the
Handheld Terminal. Use a battery pack as soon as possible after
charging it.
• For best charging results, keep the Cradle-type Battery Charger,
Handheld Terminal and battery pack contacts clean by periodically
wiping them off with a cotton swab or dry cloth.
• “L” (for left) or “R” (for right) marking is imprinted on the back of each
desktop guide and wall mount guide both accompanied with DT-930.
Be sure to install the new guides properly on the Cradle-type Battery
Charger, the desktop guides for desktop configuration or the wall
mount guides for wall mount configuration. The use of the charger with
DT-930 without replacing the original guides come installed on it with
the new guides will result in improper charging battery pack.
• However, the use of the charger with the new guides installed for DT-
900 does not result in the error.
