16.12 Microphone-hookHook Control exists as a function to control the microphone hook status for Mobile.Hook Control is the function to specify the conditions to place the transceiver in the on-hook state if both the Local MicHook and the External Hook are used. By using this function, whether the on-hook state of the transceiver when both theLocal Mic Hook and the External Hook are used is determined by AND or by OR can be changed.Also, in a Multi RF Deck/ Multi Control Head structure, whether the on-hook state of the transceiver of when the followingLocal Mic Hook and External Hook are used together is determined by AND or by OR can be changed:0 the Local Mic Hook of Control Head 1 or Control Head 2 for the Selected RF Deck0 the External Hook of Control Head 1 or Control Head 2, or the External Hook of an RF DeckThe transceiver behaves as follows according to the configuration in Hook Control (AND, OR):0 ANDThe transceiver behaves as the on-hook state if both the Local Mic Hook and External Hook are in the on-hook state.Also, the transceiver behaves as the off-hook state if either the Local Mic Hook or External Hook is in the off-hook state.0 ORThe transceiver behaves as the on-hook state if either the Local Mic Hook or External Hook is in the on-hook state. Also,the transceiver behaves as the off-hook state if both the Local Mic Hook and External Hook are in the off-hook state.The Unselected RF Deck judges the hook state of the connected RF Deck only by the input from the External Hook of theRF Deck, and performs the hook behavior.Hook Control is applied to the following configurations:0 Off-hook Scan0 Off-hook Voting0 Off-hook Site Roaming0 Off-hook Decode0 Off-hook Connect0 Off-hook Speaker RevertConfiguration using KPG-D1/ D1NConfiguring Hook Control ( Transceiver Settings > Optional Features > Optional Features 1 > Microphone-hook)16.13 GPSIn a Multi RF Deck/ Multi Control Head structure, the built-in GPS receiver unit or an external GPS receiver unit can be used.In a Multi RF Deck system, a GPS antenna is connected to RF Deck 1. The acquired GPS data is transferred from RF Deck1 to another RF Deck. Whether to enable or disable Built-in GPS Receiver can be toggled after entering GPS Mode bypressing the GPS key or Menu key, regardless of whether RF Deck 1 is the Selected RF Deck.16 MULTI RF DECK/ MULTI CONTROL HEAD16.12 Microphone-hookCommon FUNC (K, F)/Ver 2.20 300CONTENTS INDEX
