(3) POWER SUPPLY
a. Note on using dry batteries
• The BT200 model on a standard configuration
comes complete with five alkali batteries. The
unit as shipped, however, is not loaded with
these batteries. Before starting to use the BT200,
load the batteries shipped under the same cover
as instructed in Section 6.1, “Replacing Batter-
ies.”
• Use batteries of a specified voltage (1.5V).
• To avoid possible leaks, remove batteries from
the unit before leaving it out of service for an
extended period of time.
• In the case of the model with printer, printed
characters may become faint when batteries
except alkali type are used.
b. Duration of continuous operation
• When running the unit from alkali batteries: 50
hours least (if the printer is not used).
• If the printer is used, the duration of continuous
operation is reduced according to the rate of
printout (about 10 hours/1,000 lines).
c. Low-voltage indicator
• The BT200 turns on its BATTERY indicator
when the battery voltage falls. Replace the
batteries whenever the BATTERY indicator is on.
d. Autopower-off feature
• The BT200 will switch itself off automatically
when no key access is made for five minutes or
longer.
(4) CAUTION for INTRINSICALLY SAFE TYPE
• Please make sure to refer to “APPENDIX B” for
Intrinsically Safe Type.
• Intrinsically Safe type can not be modified to
equip optional printer afterward.
• Intrinsically Safe Type can not communicate by
using communication cable with 5-pin connector.
• Please use the specified baterry for Intrinsically
Safe Type.
