Test Phone Trouble Shooting
1.If there is any crosstalk in use, generally it is interference from
the telecom line so reduce the volume to reduce the
interference. Alternately, it can be a poor connection to the line
under test so check your connections.
2.If any abnormal situation is found while you are using the
CZ20252 please follow your safety procedures before
proceeding. If safe, test an alternate telecommunications line
to identify the possible fault, referring to the trouble shooting
