Automatic Discharge
Each time the AC line power is disconnected or switched off, the unit will
automatically flash-dump most of the stored power, and then discharge by resistor
the remainder of the stored power. This removes all of the flash capacitor charge to
prolong the life of the unit and is a much safer condition for storage, for
transporting, and replacement of flash tube or modeling lamp. Even if the flash tube
is defective or absent, the internal resistor will discharge all power within 30
seconds after the unit is turned off. This is a feature, over which the user has no
control.
Unit Number Assignment
This feature allows the user to assign a UNIT NUMBER (1 to 9) to each
PhotoMaster in the studio. The UNIT NUMBER is necessary when INFRARED
remote control is used with the PM400R or PM800R models (see accessories.)
To assign a UNIT NUMBER, the startup sequence will need to be interrupted. Turn
PhotoMaster AC power OFF. With the unit OFF press and hold the ½ stop “UP”
button then turn the power switch to ON, continue holding the ½ stop button until
the display reads “ir” then release the button. The Digital display should read “ir”
when you press and release the ½ UP button again, and the display will then read
“Un - 1”, or some number 1 to 9. To change the UNIT number, press and release
the 1/10 UP/DOWN arrow buttons until the desired number is displayed. To save
and close the assignment feature and save the UNIT number, press and release the
1/2 UP arrow button again. This allows the startup sequence to finish and save the
new settings. Each “R” unit’s default unit number is set at “Un - 1”. You must re-
set the unit number with the 1/10 adjustment buttons, or the default “Un 1” will
automatically be assigned.
Wireless Setup.
The “R” units are pre-set for Infrared wireless operations at the factory and no
adjustments are necessary for operation. See next section.
