Should you prefer, it is possible to switch "musical notes" to most of the
keypad keys when the keylock is On. This may be accomplished by holding
down the [4] key while switching On the receiver by the [PWR] key.
The musical notes are arranged as follows:
[1]
[2]
[3]
[4]
[5]
[6]
[7]
[8]
[9]
[0]
[PASS]
[PRIO]
[DOWN]
[CLR]
[ENT]
While this may be fun, remember that although very hard wearing, there
is always a degree of aging with mechanical devices such as keypads.
It is not too difficult to make up tunes as a party piece... try Twinkle Twinkle
Little Star !!!

[PRIO] [PRIO/SET] Priority key
The [PRIO] key is used to select the priority frequency, select the
sampling interval and toggle the priority watch On and Off.
To toggle the priority watch On and Off press [PRIO], a "PRIO" legend appears
on the LCD to confirm operation and the priority frequency will be periodically
checked for activity.
The priority frequency is selected in manual mode using the key sequence
[2ndF] [PRIO], this is referred to as PRIORITY SET.
The priority sampling interval is programmed with the key sequence [2ndF]
[PRIO] with the [PRIO] key held for more than 1.5 seconds. The range is
01 to 19 seconds with the default being 05 seconds. The value may be
changed in one second increments by using the UP / DOWN keys or [DIAL] or
by keying in a two digit number via the numeric keypad. The new value is
accepted by pressing [ENT].
