One of the surprise gifts my daughter got for her 5th birthday was a walkie talkie set from Girl Gear. Immediately after opening the set, she started talking about how she planned on using them.
Signaling for help should be learned before you have to use it. If you don't have a two way radio, cell phone or a whistle, you will need to use visual signs. Depending on what you have for material, you can either use fire and smoke, a mirror, flares, flashlight or strobe light.
Doing business online uses the same principles of what do you do with a radio earpiece a business offline, but because the internet has the potential to reach people globally in a much accelerated manner especially in terms of time, and the overheads are usually minimal or negligible, people tend to think that they need to become like super-humans in order to be able to operate such a technologically advanced system, equating what they expect to get to be equal to what they are supposed to suffer before they can obtain it.
So McBiggles and WPC Tire strolled off to the Police canteen while Eddie had to be content to sip another cup of gnat's pee from the stiff boards of his cell bed. WPC Tire - strangely enough - became disconcerted as she was called to the security stuff to relieve the duty sergeant who'd slipped out for a call of nature. She arrived back at the canteen just in time to witness McBiggles stuffing the remainder of his last bun into his mouth (one was never enough) as he jumped to his feet; flecks of saliva danced on his lips. WPC Tire saw the plate of sticky buns on the canteen counter and ran her tongue around her chops. "Right, let's see if we can slacken off Eddie's jaw bones shell we constable?" said McBiggles rubbing his hands to lose the remaining sugar. Inconsiderate Bun-hog mused WPC Tire.
The number of channels is important as well. Try to think 2-5 years in advance and think about the maximum number of channels you will need. If all of your employees will always be on the same channel, no matter what, then a 1 channel radio is right for you. If, however you need multiple channels, be sure to get the proper number. For instance, say you wanted your car valets on one channel and your wait-staff on another (they have no need to communicated with each other). But, you as the manager want to speak to both groups. Then, you will nee a radio with at least two channels. You will need at least 4 channels if you have 4 groups of people speaking at the same time, same for 6, 10 etc.
In terms of overall quality, I'm not sure these are quite as good as advertised. The walkie talkie set claims to have a range of 1,000 feet. I'm not sure it comes close to that.
After several jobs in corporate America, and more than a few bad relationships, Maggie somehow wound up in the St. Louis Metropolitan Police Academy in class 97-24.
To sum it up, I guess a little of Captain Kirk from the hit series Star Trek inspired his efforts in the development of invented cell phone technology, to the latest cell phone invention of the century.
