25.2 Routine Maintenance
25.2.1 Auto Test
• If turned off, the auto test is performed only when AC mains is connected.
• The auto test simulates the discharge test through impedances in the paddle tray. The auto test
passes only when external paddles properly contact the metal parts of the paddle tray.
• Thoroughly clean the external paddles and properly place them in the paddle tray after each use.
Otherwise, the auto test may fail or damaged external paddles may result.
• The auto test reduces the battery power. If the equipment is not connected to the AC mains
immediately, low battery may result.
• Before the auto test, check that the equipment is connected to the AC mains with a battery installed,
and external paddles are properly placed in the paddle tray or the equipment is connected with the
pads cable and 50 Ω test load. If the pads cable is not connected with the 50 Ω test load, the message
“Test load not connected with cable” appears when the auto test passes. This means that the
equipment only passes the internal discharge test, but not pass the external discharge test
connected with the test load.
25.2.2 User Test
• Do not perform the user test when a patient is connected to the equipment.
