Warm Start

The Warm Start procedure is similar to a cold start. This reset will perform a cold start

on the unit, but will not erase the Presets from memory. To perform a Warm Start:

1. Push and hold the EXIT button and PRESET buttons for a minimum of five

seconds until the Warm Start message appears on the display.

2. Once the message appears, the Warm start is complete.

Cold Start after VFlash

After a VFlash update is performed, cycle the power and perform a cold start to

continue. To perform a Cold Start after a VFlash update:

1. Turn off the power to the VTM-2000 device and wait 30 seconds.

2. Turn on the power for the device while pushing and holding the EXIT button,

PRESET button, and DOWN button. Hold the buttons until the display appears.

3. Once the quad display appears, the cold start is complete.

Updating with VFlash

The VTM-2000 is updated using the VFlash program. Obtain the latest .flu file from

www.videotek.com and follow the instructions in the VFlash User Guide located on

the VFlash CD to update the device.
