1500 Paging

1500 Paging Tone Off Time

Allows the selection of the length of the Tone Off Time for 1500 paging. The Tone On Time is as
follows:

Tone On Time = 100 ms – Tone Off Time.

OTE

This parameter affects alias paging as well.

Maximum Digits Allowed From Keypad

This parameter controls the selection of the maximum number of digits that may be entered from the
keypad by the operator. The valid range is

1500 Preamble Digits

Allows you to preset up to nine 1500 preamble digits that are transmitted prior to the digits entered by the
operator. Valid range for each digit is

TALK NOW Timer

Allows the selection of the length of time the user is allowed to talk after the paging signal. If the

TRANSMIT

button is pressed during the TALK NOW time, the unit continues to transmit until the button

is released. The range is

seconds. If

is selected, the operator is not allowed to talk after the

page.

2805 Paging

2805 Paging Tone Off Time

Allows the selection of the length of the Tone Off Time for 1500 paging. The Tone On Time is equal to:

Tone On Time = 100 ms – Tone Off Time.

OTE

This parameter affects alias paging as well.

Maximum Digits Allowed From Keypad

The parameter controls the selection of the maximum number of digits that may be entered by the
operator from the keypad. The valid range is

2805 Preamble Digits

Allows you to preset up to nine 2805 preamble digits that are transmitted prior to the digits entered by the
operator. Valid range for each digit is

TALK NOW Timer

Allows the selection of the length of time the user is allowed to talk after the paging signal. If the

TRANSMIT

button is pressed during the TALK NOW time, the unit continues to transmit until the button

is released. The range is

seconds. If

seconds is selected, the operator is not allowed to talk

after the page.
