On the system status display, not only you can see the
following information, but also you can reset the time
display and initialize the flash memory.
(1) Power voltage (EXT DC or INT DC)
This item shows the voltage of the current power source.
When the [POWER] switch is set to “INT”, this item shows
“INT DC” and the voltage of the internal batteries.
When the [POWER] switch is set to “EXT”, it shows “EXT
DC” and the voltage of the external power source.
(2) Temperature inside the unit (TEMP)
This item shows the temperature inside the unit.
The temperature significantly affects the battery
performance.
Generally, in a low temperature environment, the battery life
of primary battery (e.g. alkaline) gets shorter.
(3) Power-on time
This item shows the elapsed time since the unit is powered
on. The time display is running in realtime.
Lighting level of peak over indicator
The default is “+18 dB”. You can select between “0 dB”

: This setting allows the EMPTY indicator and the alert
for battery exchange work correctly according to the battery

item should be set correctly. Battery life depends on the bat-
tery type, battery condition and usage environment. It is rec-
ommended to exchange batteries when the EMPTY indicator
starts flashing.
