OPERATING INSTRUCTIONS
Make sure that the Model and Power switches are in the off position and the Push to
Reset button is fully depressed into its socket. Connect light head cable(s) to the Light
Unit Outlet(s) on the power supply. The outlets are wired in parallel so it does not mat-
ter in what sequence light head cables are connected.
Never connect or disconnect light units while power is on. Do not insert or remove
flash tubes while power is on. Your Brown Line power supply is equipped with arc-pro-
tection, but should your light unit or power supply malfunction, or the power cord, or
even the internal wiring in the studio be improperly terminated or defective, the chance
of arc-over when connecting or disconnecting light units is greatly increased. Severe
power supply damage and operator injury may result if arc-over occurs when light units
are being disconnected or connected. To prevent this, you should always turn the power
supply off when disconnecting or connecting light heads.
The D202 is fully compatible with all Speedotron Brown Line light units and flash
tubes.
Connect power supply cord into a 3-wire grounded AC outlet. This reduces misfires and
self-firing caused by static electricity.
Plug sync connector into Sync socket and connect the other end to PC cord for
camera. Once the camera is connected, tripping the shutter will automatically trigger the
flash.
A slave tripper (Speedotron #23510), may be inserted into the Sync socket in place of
the PC cord. In this mode of operation, the slave will activate the power supply when it
senses a bright flash of light from another light source. If the power supply fails to flash
when exposed to another light source with the slave installed in the sync socket, it may
be necessary to remove the slave, rotate it 180° and reinstall it into the Sync socket.
Turn on Power and Model switches. Wait until the amber Ready/Push to Flash
illuminates and press the button to check if the unit is operational. The light unit(s)
should flash instantly when this button is pressed. If you wish to check the function of
each individual light unit, we recommend that you turn off the Model switch and hold
your hand in front of (not inside) the light unit to be tested. When you fire the unit you
will feel the heat of the flash. This method is suggested because it is often difficult to
determine by sight if one of the lights has failed to flash.
The D202 has symmetrical and asymmetrical power distribution. The two light units are
connected in parallel when the symmetrical/asymmetrical switch is in the symmetrical
position. With the switch in the asymmetrical position power will be distributed as shown
by the power distribution table on the next page or on the side of the power pack.

Symmetrical
Any socket(s)
Asymmetrical
1 or 2 3 or 4
1 Light
2 Lights
One light: Symmetrical mode in any outlet, will receive 200Ws.
Asymmetrical mode: outlet 1 will receive 200Ws;
outlet 2 outputs 150Ws.
Two lights: Symmetrical mode, both outlets share an equal amount of power.
Two lights each receive 100Ws (200Ws divided by 2).
Asymmetrical mode: light in outlet 1 receives 100Ws;
the light in outlet 2 receives 50Ws.
Following the table will quickly illustrate other combinations that are possible with up
to four light units on the D202
