Otherwise, if the lock mode was not specified, the selected talk group can be manually
changed and the previous talk group is reselected if power is cycled. If a locked regroup
command is received, the displayed talk group cannot be changed manually or by cycling
power. It can be changed only after a clear order is received from the console.
Dynamic regrouping operates as follows:
1 When this command is received, alternating tones sound and the radio automatically
changes to the regrouping channel and “DYN REGRP” is displayed.
2 Manually select the channel corresponding to that tag. If this is not done, transmission
still occurs on the new channel, but the alternating tones sound each time the PTT
switch is pressed.
3 Talk and listen as usual. When dynamic regrouping is canceled by the dispatcher, a
short tone sounds. If a standard channel is not selected after this occurs, transmission is
not allowed if the talk group is assigned as a dynamic regrouping talk group only. If it is
assigned as a normal talk group, normal transmissions are allowed.
6.13 SmartZone and P25 Trunking Unique Features
As described in Section 3.7.2, the SmartZone
®
mode provides wide area coverage by
allowing roaming between SMARTNET and conventional sites. The P25 Trunked mode
can provide access to a single trunked site or roaming between several trunked sites.
Operation in these modes is the same as just described in the preceding sections (
6.1-6.12)
with the following additional features:
6.13.1 Busy Override
The busy override feature is enabled at the system level by the system manager and is not
a programmable radio feature. It allows a call to be placed even if not all of the sites you
are calling have a free traffic channel. The only sites guaranteed to be included are the
Critical Sites and the sites where a Critical User is located. This feature operates as
follows:
1 Assume that you have attempted to place a call and the system was busy (“BUSY”
displayed and busy tone sounded).
2 Release the PTT switch and then press it for 5 seconds or more. If a chirp-like tone
sounds with the PTT switch pressed, busy override is occurring.
Note Remember that not all members of the talk group are receiving your message. Missing
members will start receiving your message as channels become available.
