500XP
Operation (cont.)
To enter setup mode, with the unit operating, press and hold
both buttons for more than ten seconds. A melody of three
tones will be heard followed by a number of beeps that
represent the currently chosen setting. Pressing + or – allows
adjustment of the setting.
To confirm the setting, press and hold both buttons for more
than two seconds. A two tone melody will confirm exit of setup
mode.
Low Battery Warning
If the battery drops below 6.5 V, you will hear three tones of
falling frequency. Typically, with an alkaline battery, two hours
of use remain after the first warning is given.
Battery Saver Timeout
If the 500XP is operating and neither button is pressed for
five minutes, the unit will switch off to save power. This is
preceded by three warning beeps and the power-off tone of
"beep-beep-beep-boop".
Power Off
Press the
button for more than 0.5 seconds. The unit will
produce a single lower pitched tone and switch off.
