DHS-E Description
Firmware
Although all existing 3 x 8 boards can be used when upgrading an existing DHS system,
some pre-qualification must be performed. This pre-qualification will prevent noise
problems on stations that can result from a firmware incompatibility issue. This issue can
be corrected by obtaining the correct firmware from Vodavi (refer to
Caution
for further information).
