Service Manual Calibration 35
Recharger Supply Adjustments
1. Verify that the Encore power switch is off.
2. Disconnect the battery connector from P12 on the recharger board (see figure below).
3. Disconnect P8 from the Digital board (see figure below).
4. Connect the 4.9¾ test load (see “Manufacturable Test Equipment” on page 123) to
the battery connector (P12).
5. Set the power supply output to 15.0V dc.
6. Attach the dc power adapter cable to the variable dc power supply as shown figure
below.
Note
To disable the alarms while performing the calibration procedures, press
SETUP > ALL ALRM ( >YES - version 2.0 software)to remove the bell symbol
from the display. In order to inhibit the Apnea alarm, turn off Respiration
monitoring: press ECG/RESP > MORE and set RESP to OFF.
WARNING High voltages (approximately ± 200V dc or 360V ac) are present on
the recharger board when the Encore is turned on. These voltages present a
shock hazard if contacted during calibration.
Use non-conductive adjustment tools and keep fingers and conductive objects
away from the Recharger board components when calibrating.
Caution Adjustment of RP3 (step 12 on page 36) sets an overvoltage limit
which, if misadjusted, can cause fuse F1 (on the right side panel) to open. If you
suspect that RP3 has been misadjusted, turn it fully clockwise before connecting
power to the dc input jack on the Propaq Encore.
