GP328和GP338的主要功能与优点:
  
先进的音频技术
  
摩托罗拉的特殊语音压缩与低电平扩展技术，可以实现更加清脆、明晰、有力的语音质量，即使是在最噪杂的环境中也能够保持通畅无阻的通讯联系。
  
紧急告警与警报
  
轻触一个紧急按键就可以发出刺耳的警报声，为用户提供即时的救助告警提示，满足紧急通讯的要求。
  
可切换射频功率
  
优化覆盖区并节省电池消耗
  
三色LED电池电量表
  
对讲机机身上部的三色LED指示灯提醒用户在电池电量过低时及时对电池充电。
  
12.5/25kHz可切换信道间隔模式
  
任何情况下灵活而方便的信道间隔转换要求。
  
转发器/脱网工作开/关
  
通过转发器的广域覆盖自由地进行通讯，或绕过转发器直接与另一台单机联络，方便地进行本地单机对单机通讯。
  
内置语音激活传送(VOX)
  
用于非手持作业，通过对标准的头戴式送受话机来激活这一功能。
  
严格静噪/普通静噪
  
可灵活切换采用严格静噪滤除过度的背景噪声，或为普通覆盖而采用普通静噪。
  
现场改装任选插卡
  
1、实现电话接入能力的“双音多频解码”。
  
2、纪录和回放通话内容的“话音储存”。
  
  
  
GP328和GP338的其它功能
  
l                  信道扫描
  
l                  超时计时器
  
l                  私线/数字私线
  
l                  繁忙信道关闭
