After the encoding information (call number) has been entered it may be accumulated into
the keyboard stack, sent immediately, or in the event of an entry error, erased.
The Keyboard Stack
The keyboard stack provides a means of accumulating several calls prior to sending any of
them. This is useful in making best use of the channel airtime or for sending the same call
sequence over more than one channel.
To place a key sequence (call number) into the keyboard stack press the
ENTER key. If
pressing the ENTER key causes an error beep, then more information is needed by the chosen
encoding format, and more digits must first be entered. If the call number is accepted into the
stack then the display will show a blinking dash. The blinking dash indicates that the
keyboard stack contains an entry. Attempts to enter invalid key-sequences (such as live
format blocks or the instant call block) will result in an error beep and several blinks of the
display after which the number will be cleared. Over 100 total keystrokes (including pressing
ENTER) may be placed in the keyboard stack before it must be sent. If a double beep occurs
when the ENTER is pressed then the keyboard stack is full. When this happens the last call
number will not be placed into the stack, but the entire keyboard stack and this last un-
enterable call number may be sent by pressing a SEND key.
Clearing an Entry
The CLEAR ENTRY key can be used to erase a key sequence before or after it has been
entered into the keyboard stack. If digits are displayed while the CLEAR ENTRY key is
pressed then the last key sequence is erased and the display will clear (“- ”). If the display is
clear but the keyboard stack contains key sequences, then pressing CLEAR ENTRY will
cause the last key sequence to be displayed and removed from the stack. Pressing CLEAR
ENTRY
once again will clear the display. This process may be repeated until the keyboard
stack is completely erased. If pressing CLEAR ENTRY caused a beep then the keyboard stack
is empty and there are no key sequences to clear. A convenient way to erase the entire
keyboard stack is to press
RESET.
Sending a Call
Pressing a SEND key causes the last unstacked call code to be forced into the keyboard stack
(if acceptable) even if the double beep indicated it was full. All call numbers sent over the
manually chosen channel are taken from the keyboard stack in the order in which they were
entered (first call number entered is the first call sent). Prior to sending, the encoder may
monitor the channel busy signal for the selected channel. If a channel busy signal is used and
it indicates busy then, the encoder will inhibit transmission until either the channel becomes
clear or until the SEND key is again pressed. For up to 30 seconds, the encoder will beep and
flash the word “bUSY” after which the attempt to send will be abandoned. Once the
transmission begins, it may be canceled only by pressing the RESET key. After the send
sequence is complete, the display will rapidly blink the last four digits of the last call number
sent. These blinking digits in the display indicate that the keyboard stack may again be sent
on the same or different channel by pressing the
SEND key for the desired channel. After 30
