A-10 Technical Data
Battery Information
In case of power failure or other system error, the batteries in the Merlin PSA support operation of the
unit at the maximum Pulse Amplitude settings in all channels and at the maximum Base Rate setting
for at least 30 minutes.
1
The batteries do not power the screen of the Merlin PCS. The yellow Battery
LED on the Merlin PSA lights up when the unit is operating on battery power and pacing is enabled.
When the yellow battery LED is flashing, the batteries are near depletion. They should be replaced
immediately.
During a power or system failure, the Merlin PSA operates in Safe Pacing mode for as long as the
battery life permits. To ensure that the battery life is sufficient, the Merlin PCS measures the Merlin PSA
battery voltage when the Merlin PCS is turned on. If the batteries cannot sustain PSA operation for at
least 30 minutes, you will see an on-screen alert at the beginning of a session that indicates the
batteries are near depletion and should be changed.
To install new batteries:
1. Disconnect any leads and patient cables from the Merlin PSA.
2. End the PSA Session and turn off the Merlin PCS programmer.
3. Lift the Merlin PSA unit from the storage compartment and remove the connections from
the Merlin PSA to the Merlin PCS.
4. Locate the blue battery compartment hatch (door) on the bottom of the Merlin PSA.
5. Push down the tabs on the door and lift the door open.
6. Remove all four batteries.
7. Insert four new, high-quality AA-size LR6 (alkaline) batteries into the compartment. Install
the batteries according to the polarity symbols (+ and -) marked inside.
8. Close the battery compartment door and replace the Merlin PSA into the storage compart-
ment of the Merlin PCS.
9. Turn on the Merlin PCS and start a PSA session.
1. The 30-minute estimate assumes an operating temperature of 20-40°C and the use of high quality alkaline
batteries. Battery performance is reduced at temperatures below 20°C.
Note
If the system alerts you that the batteries still need to be replaced
after you have replaced the batteries, then:
• You did not turn the Merlin PCS off before changing the batteries
• You installed the batteries incorrectly
• The batteries have insufficient voltage.
Repeat this procedure, paying close attention to the polarity sym-
bols in the battery compartment.
