Forward Error Correc on
Forward Error Correc on places extra bits in the transmi ed data so receivers can check for transmission errors. Al-
though data throughput is adversely aff ected, using Forward Error Correc on can greatly improve range and so is strong-
ly recommended.
Note: The Forward Error Correc on screen is not displayed when using Trimble protocols, which do not
support forward error correc on.
Error Codes

What to do
• Error Code 01-02: Check ba ery or power supply voltage level; check power cables; recharge or replace the
ba ery; check the charger.
• Error Code 08: Place the radio in the shade; check the antenna and antenna cables for damage or
disconnec on; set radio link rate to 19200 to reduce the duty cycle.
• Error Codes 11-12: Turn the radio off and wait a full second before turning it back on. If the radio s ll reports
Error Code 11 or 12, the SRAM memory may be corrupted and you should contact Customer Service (see
