I have the manual in I think textyt and a very nice version someone did 
in html.  I don't remember where I got it, but I can send along if you 
don't have already.  I'd have to look in the manual, but I think you 
hold in the tone button while powering on, let me go look.
Here is what the manual says
Cross-band Repeater:
If receiving a signal on the TX band, the transceiver
switches the current RX only band to the TX band. This is useful when 
joining
in a group talk. Participants in a group talk need to set a receive and 
transmit
frequency on different bands so as not to miss any conversation within 
the group.
1 Enter Menu mode and access Menu 403 (RPT.MOD).
2
  Set the Repeater operation mode to CROSS (cross-band), A-TX (A band), 
or
B-TX (B band).
3 Turn the transceiver power OFF.
4 Press [TONE] + Power ON.
  The Repeater mode is ON and the
and icons blink on the display.
  You are unable to perform any transceiver functions while in Repeater 
mode.
  To return to normal operation, turn the transceiver power OFF, then 
press
[TONE] + Power ON.
Note:
You cannot activate the Repeater function while in single band operating 
mode or
Weather Channel mode.
Activating the Repeater function switches OFF the Automatic Simplex 
Checker (ASC).
The Time-Out Timer is locked at 3 minutes.
Resetting the transceiver will not cancel the Repeater mode.
