Maintenance Activities
Frequency Activity Actions to be T aken
Daily
Monthly and after
each use
Check the i-PAD NF1200 for any error
messages that might have been
generated during the Daily Periodic
Self-Test.
Check supplies, accessories, and spare
parts for damage and expiration.
Initiate complete self-test by doing a
Manual Self-Test.
Check the case of the i-PAD NF1200
and the accessories for any sign of
apparent damage.
Check for dirt contamination.
If a message that the battery is low is
displayed, recharge the battery. For any other
error messages, please call the manufacturer
or its designated service center.
If any supplies have expired, replace them
immediately.
If the self test detects any problem, see the
chapter on Troubleshooting.

2.4 Batteries
The i-PAD NF1200 is equipped with LiMnO2 battery cells. These batteries are nonrechargeable. The status of the
battery charge is monitored by periodic tests (daily, weekly, monthly), power ON test, run-time test, and battery
insertion test. The i-PAD NF1200 indicates through the State LED and the i-Button if the battery pack needs to be
replaced.
If the voltage level of the internal Battery pack falls below the minimum tolerable level, the i-PAD NF1200 is
going to be inoperative.
If this is detected during automatic self-test, the i-PAD NF1200:
a. Flashes the State LED in red
b. Emits a burst of beeps every minute.
When the i-PAD NF1200 is turned ON after a low battery condition is detected, the i-PAD NF1200:
a. Turns the State LED momentarily in blue.
b. Then turns the State LED in solid red.
c. Flashes .the i-Button in red
d. Gives the prompt: “Press the flashing red i-Button”.
e. After the i-Button is pressed, the i-PAD NF1200 gives the prompt: “Low battery. Replace the battery with a
new one.”
The sequence of indications from a to e above is also given when the low battery level is detected during battery
insertion test.
• Do not charge the battery pack
• Do not open the case of the battery pack. Do not saw off or break apart the case of the battery pack.
• Do not let the battery pack come into contact with open flames and other hot objects. Do not dispose
of in fire
• Do not short-circuit the terminals of the battery pack.
• Do not subject the battery pack to serious physical impact. Do not hit it with a hammer.
• In case of leaka
• Keep the battery pack out of children’s reach.
• If the battery pack, leaks and the leaked liquid gets in the eyes, wash them with clean water and
consult a physician immediately.
• Do not leave the battery pack in direct sunlight or in high temperature areas.
• Do not have the battery pack in contact with water.
• Keep the battery pack away from direct sunlight, high temperature, and humidity.
• Follow local regulations when disposing of the battery pack.
• Do not subject the battery pack to conditions beyon d the safe environmental conditio ns for the i-PAD
NF1200.
e or strange smell, keep away from fire to prevent ignition of any leaked electrolyte.
