Artikelnummer:331160338628REALISTIC (RADIO SHACK) PRO-39, CATALOG # 20-303, PROGRAMMABLE SCANNER RECEIVER!. Realistic Pro-39 handheld scanner comes with a external power adapter and a external Realistic Speaker. Scanner works perfectly and is in very good condition. ******************************************************************************************************************************************************************************************************************************* This Realistic PRO-39 Programmable Scanner lets you in on all the action!
It gives direct access to over 31,000 frequencies, including those used by
the police department, fire department, ambulance services, amateur radio
operators, and transportation services. Frequencies can be stored in 200
channels which allow selections at any time.
The secret to this scanner's ability to scan so many frequencies is its
custom designed microprocessor, a tiny built-in computer. This scanner's
microprocessor also gives these special features:
Hyperscan-lets you search through frequencies at up to 50 steps per second
or scan stored channels at 25 channels per second.
Ten Channel-Storage Banks-let user group stored frequencies which can
easily identify calls.
Liquid-Crystal Display-shows the selected channel and frequency.
Two-Second Scan Delay-helps prevent the loss of replies on a channel while
scanning.
Memory Backup-keeps the channel frequencies stored in scanner's memory for
up to 1 hour without the battery.
Lockout Function-makes scanner skip over specified channels.
Priority Channel-helps user keep from missing important calls on the
selected priority channel.
Monitor Banks-allows user to save up to ten channels located during a
frequency search. Frequency Coverage:
