Abstract
Description
アンテナ素子26は、アンテナ・インピーダンス及び制御スイッチ46にインタフェースされる。アンテナ・インピーダンス及び制御スイッチ46は、外部アンテナ・コネクタ及びスイッチ48に更にインタフェースされる。LCD画面28はLCD電力制御ブロック50によって制御され、LCD画面28の輝度は、輝度コントローラ(LPF)52によって制御される。
走査前に信号が許容可能である場合に前述のことが生じる。しかし、許容可能でないことがあり得る可能性が存在する。その場合、ソフトウェアは、走査を開始するか、又は待つかを決定する。この決定に影響を及ぼす因子には、最後の走査以降に経過した時間、一次受信器に入ってくる信号の現在の状態、外部電力が印加されるか否か、及びバッテリ・レベルがある。
