MAINTENANCE
NOTE:
It is recommended that the battery in the PTS ii be tested as described below every 3 months and replaced annually.
Even when the PTS ii is used on AC power, the battery pack must be in good condition to provide backup power in the
event of the AC power being disconnected
BATTERY TESTING
To determine if the battery pack needs replacement, charge it for at least 5 hours and then test as follows:
•
Remove the AC power supply and power up the PTS ii. The BATTERY STATUS indicator should be
1
completely filled with 5 green bars
2
•
Connect the PTS ii to a tourniquet cuff and inflate to 350 mmHg
3
•
If only one red segment shows after 1 hour, replace the battery pack
If battery runtime is much shorter than previously experienced, consider replacing the battery pack.
NOTE:
The battery pack must also be replaced if a "BATTERY FAILURE" alarm condition occurs (Refer to Alarm Conditions
under Section 2 Operating Instructions) that cannot be corrected by plugging the PTS ii into AC power or by confirming
that the battery pack is securely connected. You may also wish to replace the battery pack if you regularly use your PTS ii
on battery power and have LOW BATTERY alarm conditions occurring soon after a full charge
BATTERY PACK REPLACEMENT
Follow the procedures below to replace the battery pack:
•
Remove the single battery cover screw from the back of the PTS ii (directly above the label) and remove the battery
cover
•
Unplug the battery by pulling the battery wires straight up from the battery compartment and remove the old
battery pack. This will disconnect the battery connector from the four-pin plug inside the PTS ii. Recycle or dispose
of the old battery pack in accordance with local regulations and procedures
•
Install the new battery pack supplied by Delfi by aligning the keyed plug and pushing the connector onto the four-
pin plug inside the PTS ii. Push the connector all the way down until it stops. The top of the connector will be about
flush with the battery compartment surface. The connector cannot be installed the wrong way; if it will not slide
easily all the way down, rotate it one-half turn and try again
• WARNING:
Use only Delfi NiMh battery packs (REF 7-2200-007). Do not use any other batteries. Use of improper
batteries may cause irregular operation that could be hazardous to the patient and/or user and may permanently
damage the PTS ii, voiding the warranty
• WARNING:
When a new battery pack is installed, the PTS ii must be plugged in to AC power for at least 5 hours to
fully charge the new battery before use
