In IGS Mail 3081 I described the external frequency settings for firmware
version RD00 but did not state the firmware version.  The settings for CD00,
which is also commonly used, were not provided, and they are somewhat
different.  This has caused some confusion for which I apologize.

The following are the correct settings for firmware CD00.

1. Input external frequency in the EXTERN FREQ Menu. 

2. AUTO-SWITCH N will not use internal oscillator if external frequency is
lost. Y Will use internal oscillator if external frequency is lost, but will
use external reference when available.

3. Under RCVR CTRL set Clock Steering to N

The frequency and auto-switch settings should be saved through the power
cycle by default.
