Charging and Discharging the Batteries
New Ni-MH batteries must be fully charged prior to use. A new Ni-
MH battery's full performance is achieved only after a number of
complete charge and discharge cycles. A fully charged battery will
run for approximately 4-5 hours. (Note: Perc sensor heads require
more power and will run for a shorter time)
Charging Instructions
1)
Plug in the adaptor
2)
Turn
the
monitor
on
3)
Allow 15 hours for the battery to fully charge.
Note:
•
During charging the battery symbol on the display flashes
slowly.
•
The battery can be charged with the sensor head installed or
removed from the base. (Remember to switch off the monitor
before removing the sensor head).
•
Unplugging the main power will reset the above charging condi-
tions.
•
The batteries can be charged and discharged many times but
will eventually wear out. When the operating time is noticeably
shorter than normal, it is time to replace the batteries.
•
It is not necessary to fully discharge the batteries. When not
using the Series
200
Monitor as a portable unit, always plug in
the mains adaptor to recharge the batteries with the monitor
switched on
.
•
If left unused a fully charged battery will discharge itself over
time.
Note:
If you have difficulty charging the battery, either:
A)
Replace the battery
B)
Contact Aeroqual with the software version number
(see section 3.3 to locate the version number.)
