TROUBLESHOOTING
Error Codes
Your HTX-242 has the following three built-in error codes.
tF Err
—appears if you try to transmit outside the allowed range
(see “Extending the Transmit Frequency Range” on Page 16).
PLL Err
—appears if the HTX-242’s PLL (phase-locked loop) sec-
tion malfunctions. If turning the HTX-242 off then back on does
not correct this error, take it to your local Radio Shack store to
arrange for service.
EEP Err
—appears if the HTX-242’s EEPROM checksum fails. Try
resetting the HTX-242 (see “Resetting the HTX-242” on Page 16). If
this does not clear the error, take it to your local Radio Shack store
to arrange for service.
