1. Optional on some Test Set models.
CAUTION: Connecting a signal of >200 mW to the ANT IN (antenna) port can cause instrument damage
(although internal protection circuits can typically withstand a short-duration signal of 1 or 2
Watts). If the overpower circuit is triggered, remove the signal from the ANT IN port and turn
the Test Set off and on to reset it.
