Ignition Switch

When either "Tx Inhibit", or "PTT Tx Inhibit" are selected, the Emergency Power Up feature is not allowed.

When a Conventional or Trunking Tx Inhibit (TxIN) menu-selection is CPS-configured, this field must not be set to "Tx Inhibit" or "PTT Tx inhibit"; otherwise the CPS considers it to be invalid.

For a Dual Radio configuration:

• When the Radio Selection field is set to "Secondary Radio" and Enable Secondary Radio Tx is enabled, this field must be set to "Blank", "Tx Inhibit" or "PTT Tx inhibit" in order to be considered valid; however, when the Radio Selection field is set to "Secondary Radio" and Enable Secondary Radio Tx is disabled, "Blank" is the only valid selection.

• Only the "Primary Radio" checks for an Emergency Power Up footswitch-press or if the "Ignition" state is present (or removed), to determine whether the radio can power-on (or power-off)

• When the Dual Radio configuration powers-on, the selected radio always defaults to the "Primary Radio".

SELECTIONS:

DEFINITIONS:

• Radio powers-on with a radio-user Power On button / knob selection.
• Radio powers-off with a radio-user Power Off button / knob selection, or when the Inactivity Auto Power Off timer expires.
• While "Ignition" is not present, certain communications are not possible:

• The radio does not register with ASTRO 25 (APCO) - Trunking Systems and therefore cannot receive this type of Trunking communications (see the System Type field), however Type II Trunking Systems can receive dispatch without being registered.
• Also, the radio cannot be powered-on with the Emergency Power Up feature, and Emergency Alarm transmissions using the Emergency Power Up footswitch are not possible.

PTT Tx Inhibit

• Radio powers-on with a radio-user Power On button / knob selection..
• Radio powers-off with a radio-user Power Off button / knob selection, or when the Inactivity Auto Power Off timer expires.
• While "Ignition" is not present, all PTT button transmissions are inhibited:

• The radio does not register with ASTRO 25 (APCO) - Trunking Systems and therefore cannot receive this type of Trunking communications (see the System Type field), however Type II Trunking Systems can receive dispatch without being registered.
• Also, the radio cannot be powered-on with an Emergency Power Up footswitch-press; however, the footswitch can be used to initiate Emergency Alarm transmissions.
