When you do dial (ZAP/g1/number) you can do instead:

#  g: select the lowest-numbered non-busy Zap channel (aka. ascending 
sequential hunt group).

# G: select the highest-numbered non-busy Zap channel (aka. descending 
sequential hunt group).

# r: use a round-robin search, starting at the next highest channel than 
last time (aka. ascending rotary hunt group).

# R: use a round-robin search, starting at the next lowest channel than 
last time (aka. descending rotary hunt group).
