Sera ya KurudishaZawadi ya Bure
Karibu Roymall, tovuti yako ya kitaalamu ya kununua zawadi za hifadhi ya duka. Tunathamini na kushukuru msaada wako, na tunataka kuonyesha shukrani yetu kwa kuongeza kipengele cha msisimko wa ziada kwa ununuzi wako. Unaponunua nasi, sio tu utapata bidhaa za hali ya juu zinazoboresha maisha yako, lakini utapata pia zawadi ya bure ya kipekee kwa kila agizo lako. Tayari kuchunguza mkusanyiko wetu na kupata zawadi zako kamili? Chunguza uteuzi wetu wa bidhaa za hifadhi ya duka, weka agizo lako na subiri msisimko wa zawadi yako ya bure kufika pamoja na ununuzi wako.Sera ya Usafirishaji
Tutafanya kazi kwa bidii kukufikishia bidhaa baada ya kupokea maagizo yako na kuhakikisha zinafika salama. Maelezo ya uwasilishaji yatakuwemo kwenye barua pepe yako ya uthibitisho.Kwa hali ya kawaida, maagizo huchakatwa ndani ya siku 2. Katika hali maalum, yanaweza kucheleweshwa kama ifuatavyo: Unapoagiza Jumamosi, Jumapili au siku za likizo, itacheleweshwa kwa siku 2.Kwa kawaida, inahitaji siku 5-7 za kazi (Jumatatu hadi Ijumaa) bila kuathiriwa na ucheleweshaji wa ndege au mazingira mengine.Kwa sababu huduma yetu ya usafirishaji ni kimataifa, muda wa uwasilishaji utategemea eneo lako, kwa hivyo inaweza kuchukua muda na tafadhali subiri kwa subira ikiwa uko katika wilaya au nchi za mbali.1. Sera ya Kurudisha na Kubadilisha
Tunakubali tu bidhaa zilizonunuliwa kutoka roymall.com. Ikiwa unanunua kutoka kwa wasambazaji wetu wa ndani au wauzaji wengine, huwezi kuzirudisha kwetu. Bidhaa za mauzo ya mwisho au zawadi za bure hazikubaliki kwa kurudisha.Ili kuwa na haki ya kurudisha, bidhaa yako lazima isitumike na iwe katika hali ileile uliyoipeleka. Pia lazima iwe kwenye pakiti ya asili.Baada ya kupokea maagizo ya kurudisha kutoka kwetu, tafadhali pakiti bidhaa zako zilizorudishwa na kuacha kifurushi chako kwenye ofisi ya posta ya ndani au mtoa huduma mwingine wa usafirishaji.Tutachakata bidhaa yako ya kurudisha au kubadilisha ndani ya siku 3-5 za kazi baada ya kuipokea. Rudi pesa itachakatwa na kuwekwa kiotomatiki kwenye njia yako ya awali ya malipo.Hakuna kurudisha au kubadilisha kunaweza kukubaliwa ikiwa bidhaa ilitengenezwa kwa maagizo maalum, ikiwa ni pamoja na saizi maalum, rangi maalum au uchapishaji maalum.Ikiwa unahitaji msaada zaidi, tafadhali wasiliana nasi. service@roymall.com au Whatsapp: +8619359849471
2. Sera ya Kurudisha Pesa
Utapata rudi pesa kamili au stoo 100% ya stoo baada ya kupokea na kukagua kifurushi kilichorudishwa. Rudi pesa itachakatwa kiotomatiki kwenye njia yako ya awali ya malipo.Tafadhali kumbuka kuwa gharama za usafirishaji na ushuru wowote au ada hazirudishiwi. Gharama za ziada za usafirishaji hazirudishiwi mara tu kifurushi kimetumwa. Wewe ndiye mwenye jukumu la kulipa ada hizi na hatuwezi kuziacha au kuzirudisha, hata kama agizo litarudishwa kwetu.Mara tu tutakapopokea na kuthibitisha bidhaa yako iliyorudishwa, tutakutumia barua pepe kukujulisha kuwa tumepokea bidhaa yako. Pia tutakujulisha kuhusu uthibitisho au kukataliwa kwa rudi pesa yako.Ikiwa una shida yoyote kuhusu mchakato wa kurudisha pesa, tafadhali wasiliana nasi. service@roymall.com au Whatsapp: +8619359849471Note:
If you want to use Gemini mode, you need to use a TX that supports Gemini mode.
Description:
iFlight ELRS diversity receiver is a dual-antenna true diversity receiver developed in close cooperation with the ExpressLRS Team. ExpressLRS is known for its long-range operation, low latency, and high-power telemetry feedback capabilities.
The ELRS diversity receiver features well-placed dual antennas with shielding covers, enhancing its resistance to interference, widening signal reception, and ensuring a more stable connection compared to conventional single-antenna receiver systems.
It incorporates a TCXO temperature-compensated crystal oscillator to prevent frequency shift caused by temperature variations. It significantly meets the reliability requirements for long-distance flights, aerial photography, or FPV freestyle maneuvers.
Features:
* Gemini mode and True Diversity mode are compatible, better reception effect.
* Integrated shields can protect electronic components and enhance anti-interference capabilities.
* Newly upgraded Temperature Compensated Crystal Oscillator, lower packet loss, high-frequency stability
* Up to power 500mW(868MHz/918MHz)/250mW(2.4G) telemetry transmission, resulting in stronger telemetry signals and significantly reducing instances of telemetry loss.
High-performance at 2400MHz or 900MHz (915 / 868 bands available)
Performance and Compability:
Make sure to install the antenna away from conductive or magnetic components (carbon, metal, motors).
Flash the latest firmware and follow the ELRS Community for updates, tutorials or contributions.
Use iFlight ELRS receivers coupled with our transmitter for maximum performance! We"ve probably achieved market"s best crystal frequency stability at a very low frequency deviation. Please checkout this article for further information https://github.com/ExpressLRS/ExpressLRS/wiki/Crystal-Oscillator-(XO)-Frequency-Error
Band Option:
The 900MHz as well as 2400MHz band have outstanding performance and long range capabilities. If you"re not sure what to get, please checkout the official ELRS Long Range Competition to see what has been achieved. https://www.expresslrs.org/2.0/info/long-range/
What can you expect? Due to local regulations, the 915MHz FCC region seems to have a better performance than the 868MHz EU region. The 2400MHz band works great in any region, has a higher packet rate up to 500hz. This is not a common 2400MHz protocol and cannot be compared to anything prior on the market.
