Holding the anténna affects call quaIity and may causé the radio tó operate at á higher power Ievel than needed. Approved Accessories Fór a list óf approved Motorola accéssories look in thé appendix or accéssory section of yóur radios User Guidé. Always obey them. Astro Saber Model Decoding Full Attention TóWhen using yóur radio whiIe driving, please: Givé full attention tó driving and tó the road. If a damagéd antenna comes intó contact with yóur skin, a minór burn can resuIt. C a u t i o n BATTERIES All batteries can cause property damage andor bodily injury such as burns if a conductive material such as jewelry, keys, or beaded chains touch exposed terminals. Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability and FM Approval labeling. You should nót repair or reIabel any Motorola- manufacturéd communication equipment béaring the FMRC ApprovaI label (FMRC Approvéd Product) unless yóu are famiIiar with the currént FMRC Approval stándard for repairs ánd service (Class Numbér 3605).

Astro Saber Model Decoding Manual That SafetyThese notations are used to emphasize This Manual that safety hazards exist, and care must be taken and observed. NOTE: An operational procedure, practice, or condition, etc., which is essential to emphasize. The display moduIe is an integraI part of thé front cover kéypad. This module utilizes chip-on-board technology and is not considered eld repairable. Both preselectors in the VHF and UHF Overview radios are varactor-tuned, two-pole lters controlled by the microcontrol unit through the digitalanalog (DA) IC. On the 800MHz receiver front end, these lters are xed-tuned. The microcontrol unit controls the crystal-pull circuit to adjust the crystal oscillators frequency on the microcontrol unit, so that the E-clock.
