Cleaning Instructions
Clean the VR2C with a damp cloth and mild detergent.
Do not use solvents
. Do not use a scraper or
abrasive cleaner on the LED window or the seal surfaces.
5.2
Battery
The VR2C can be powered externally from a DC power source and/or internally by a single “D” size 3.6
Volt Lithium battery with a connector attached – the Tadiran TL-5930/F. The VR2C is shipped in Suspend
Mode with the internal battery connected.
5.2.1
Battery Life
The amount of battery life remaining is displayed when the VR2C is connected to
the VUE software and is also available as part of the ASCII Status response. A
warning window will appear in VUE when the internal battery level is low and the
battery needs to be replaced.
When external power is not present, a new Lithium D-cell internal
battery will last approximately 10 months in a VR2C-69kHz and
approximately 6 months in a VR2C-180kHz. This battery life can
vary somewhat depending on how often the VR2C communicates
serially with the host processor.
When external power is supplied to the VR2C, the internal battery will typically last for 10 years.
When a VR2C will sit non-deployed for an extended period of time, place it in Suspend Mode to save
battery power (see either section 3.1.8 or 3.2.6.5).
The VR2C is shipped in Suspend Mode with the internal battery connected.
Put the receiver in Record Mode (start a study) before deployment.
