1.3.3 BATT.SET switch and LED

Any model-LQP525 or LQP527 CMU module is equipped with a BATT.SET switch (battery
replacement switch) and a BATT.SET LED indicator. The BATT.SET switch is used to
initialize a count of the number of hours of use (battery life) that is maintained in the CMU
module's main memory. When the BATT.SET switch is pushed, the date and time of the
pushing is recorded in the CMU module's program storage memory. This switch is used when
you first use the CMU module or when you replace the battery module (model LQZ500)
connected to the CMU module. When you first use the CMU module, perform the following
procedure:
① Mount the CMU and the battery module on the S10V mount base.
② Power up the S10V controller.
③ Connect the battery cable to both the CMU and the battery module. Be sure to connect this
cable in a power-on state.
④ Push and hold the BATT.SET switch until the BATT.SET LED comes on. As soon as the
BATT.SET switch is pushed, the USER LED starts flashing (this is no error), indicating that
the date and time of the pushing (battery replacement) is being recorded in the flash memory.
⑤ When the BATT.SET LED is lit, release the BATT.SET switch. This procedure ends when
the BATT.SET and the USER LED both go out.
For information on how to replace the battery module, see the description under "6.3.1
Replacement procedure."
