The Right IP Rating For Your Business

The IP code that comes in connection with your chosen radio may be somewhat of a confusion to the average user. The official meaning behind this code is to classify the degree of protection your radio has against intrusion, covering things such as dust and water immersion for set periods of time.

The two digits following the IP both stand for protection against different substances, for example the first number is in terms of solids that your radio may come into contact with, whilst the second being in relation to water. Solids range from a rating of 1 through 6, whilst water is protected from a rating of 1 through 9K. Should a digit of 0 appear in either the solids or liquids position, then this indicates that the radio is not protected against said material.

Radios without an Ingres protection would be IP00, although this is extremely rare for a two way radio to have no Ingres protection, with the most common protection rating from manufacturers such as Motorola and Hytera being IP54. This covers the radio for a limited Ingres protection against dust, whilst also being safeguarded against splashes of water from all directions.

ATEX radios are designed to be used in some of the most dangerous working conditions in the world, environments such as mining, oil refineries and power plants are common places for these types of two way radios. Due to the high level of danger in place, the IP rating tends to be higher at IP67. This rating not only conceals the radio completely against dust, but also protects the radio from immersion in water up to 1 meter deep for around 30 minutes.

Differentiating working environments will determine the level of Ingres protection you will need for your radios, for example in an education environment purchasing radios that are IP68 rated would be completely unnecessary, where radios that are IP54 would be the more logical choice. Leisure centres can be dependent on the fact of if there is a swimming facility, should this be the case then a radio that is IP67 and protected against immersion in water would be a better fit.

Tips For Effective Communications

When using two way radios there are generally some unwritten rules on how to make best use of your communication devices. In order to make conversation easier between yourself and the recipient, various methods can be used.When first pressing the push to talk (PTT) button take a brief moment before relaying your message, this because there is a short delay with most radios before it begins to transmit. On newer releases of radios brands have began implementing a feature called time to talk, this sounds a bleeping noise until the radio is ready to transmit meaning that none of the communications are missed. Some radios that have this feature are the Motorola DP1400 and the Hytera PD505, although almost all current digital radios have implemented this feature.

Shorter talk time is also seen as the most effective way of communicating with colleagues. Due to only one person being able to transmit at a time, making a statement then waiting for acknowledgment before continuing with your next point allows for the person you are talking to being able to either agree or ask for further information on the subject. General terms are often used in radio communications, these may be things that you have previously heard not only via your own personal radio communications but in films and TV programs alike.

Radio Check – Can You Hear Me?
Read You Loud & Clear – Response to “Radio Check” Meaning Transmission is Good
Go Ahead – Ready To Recieve Transmission
Stand-By – Acknowledging the Message, But Unable To Respond
Roger/Ten Four – Message has been recieved/understood
Negative – No
Affirmative – Yes
Say Again – Repeat Your Message
Over – Message Completed
Break (x3) – Interruption due to Emergency
Come In – Asking second party to acknowledge they can hear you
Copy – You understand what has been said
Wilco – Meaning “I Will Comply”
Repeat – Used before repeating transmission

Identification is key in two way radio conversation, this because as mentioned before only one message can be transmitted at a time. Therefore, if a channel is populated with multiple radios in use, it may be unclear to other users who the message is directed towards. Identifying both who it is sending the message, and who it is targeted towards, unless of course it is aimed at a group of people then this should be made clear.

The NATO Phonetic Alphabet is the most widely used radiotelephone spelling alphabet. Created in order to avoid confusion, the Phonetic Alphabet allows for clear communications so that nothing is missed or misspelt. Recognised in a variety of languages, this alphabet is something that Radiotronics highly endorses to any company purchasing two-way radios, as if the work force is aware of it then it can make communications much more efficient.

Motorola Housing Front Cover Guide

Motorola offer housing (front cover) kits for almost all of their portable and mobile two way radios. But it is an absolute minefield of part codes. For this guide we’ll concentrate on rehousing kits, that’s complete kits, not the components themselves.

This article is work in progress. If you have a radio not listed, email spares@radiotronics.co.uk wth your model of radio.

What’s the difference?

A two way radio housing kit from Motorola usually contains quite a few parts that makes changing the housing relatively simple.

The DP4000 (non-E) series has 6 models and does not have a front name badge. The model badge is on the rear of the radio on the top Back Panel above the battery.

As an example, to fully refurbish a DP4400 you would need 1x PMLN5691 housing, 1x 15012092001 back panel, 1x 36012004001 volume knob, 1x 36012005001 channel knob and finally, 1x 15012157001 accessory socket dust cover.
