T2020 Operator's Manual

keying the label or acronym into it, until it has enough characters to be able to
distinguish the word from all similar words it has in its memories.

For example:

Suppose your radio has two channel labels programmed into it:  BASE and
BASIL.  To call up the BASE channel, you key in [A

B

C]; [

A

BC]; [PR

S

].  The

radio cannot yet distinguish whether you want BASE or BASIL so it places
"***" in the display.  But when you key in the fourth letter, [D

E

F], the radio

knows you do not want BASIL (or you would have keyed in [GH

I

]) and so it

is able to acknowledge the entry properly and displays "

BASE

".

Note that in choosing labels or acronyms, you should avoid words which are
indistinguishable to the radio, e.g. BASE and CAPE.  Both use the same key
sequence, [ABC]; [ABC]; [PRS];  [DEF].  You will only be able to find them
separately with the 

 or 

 keys.

 or 

 

 or 

 

When the "

>?

" indicator appears in the display, these keys act as up / down

scrolling keys to enable you to search through a list of choices.  They are used
in conjunction with the 

 and 

  keys.

When the "

>?

" indicator is not visible in the display, these keys act as dialling

keys for Selcall and DTMF dialling.  In Selcall dialling mode the 

 key

may be used in place of the 

 key, and the 

 key may be used as a 'wild

card' digit to make group calls.

  'Call' indicates that your radio has received a Selcall call.  If it is intended

specifically for you alone, your radio will also sound a ringing tone, 

burr,burr

...burr,burr

.  If the call is a group call intended for several users at once, your

radio will sound only one sequence of this ringing tone, 

burr,burr.

  If the 'Call'

indicator is flashing, your radio received a call which you were unable to
answer.  It will only indicate who the call was from if that option is fitted.
