Refer to Figure 1 when recharging NiCad batteries and proceed as follows:
a. Be certain that the battery pack power cord is connected to the power cord
receptacle on the back panel of the audiometer - ( A )
b. Connect the instrument power cord to the receptacle on the lower edge of the
battery pack - ( B ).
c. Plug the power cord into a wall outlet.
CAUTION
!
Although no damage to the rechargeable NiCad batteries
will occur if the pack is left charging for more than the 18 hours required
for a full charge, the batteries should not be left charging for extended
periods several days) because the useful life of the rechargeable NiCad
pack will be shortened. Welch Allyn recommends unplugging the battery
pack power input cord from the back of the audiometer and plugging the
main line power cord into the jack if main line power is to be used most
of the time.
