10 — 15 hours. Overcharging may damage electronic components of the
calculator and therefore shorten calculator life.
Oniy nickel cadmium batteries may be used for recharging. Use of any other
type of battery for recharging will result in damage to the calculator,
И the nickel cadmium batteries do not charge please check:
A) If the polarity on the batteries match the polarity (+ or —) on the battery
terminals.
В} If any of the battery terminals are rusted.
C) If the charging time was indeed 10 ~ 15 hours.
if all of the above is checked and the batteries are still not charged return
to the store where the calculator was purchased and try charging the
batteries on the store charger, and with another set of nickel cadmium
batteries,
How to change rechargeable batteries.
To change the rechargeable batteries, make sure the power switch is on
“OFF”, Remove the battery access cover from the back of the calculator
by moving the access cover toward the bottom of the calculator, Remove
and discard the old batteries. Before placing in your new batteries note
the polarity. Be sure to match the battery polarity with the corresponding
terminals. |

It is highly recommended that rechargeable batteries be used with this calcu-
lator, Since your charger is also your A/C Adaptor, The rechargeable batteries
must be removed when the A/C Adaptor is used. To avoid damage use only
unisonic Model 623 or Model SY-1200 or Model 620 charger/adaptors for your
calculator, In the event that disposable AA penlight or carbon zinc batteries are
used no attempt should be made to recharge them as this will result in serious
damage to the calculator. Therefore, since the charger is your A/C Adaptor, all
disposable batteries should be removed when the A/C Adaptor is used.
It is not advisable to switch off between rechargeable and non rechargeable
batteries continuously, as this may lead to the effors mentioned above. Do not
handle rechargeable batteries unless they need changing or recharging.
